Solar workflow depth
Can the product carry system details, proposal status, project milestones, and the delivery handoff without rebuilding the process in custom fields?
Quickest Solar CRM ranks first under our proposal-first value and adoption lens. This guide discloses that commercial relationship and every unverified Czech capability, then compares six alternatives across CZK quotations, VAT, EDC, distribution-company connection, export-sale assumptions, Czech documents, GDPR, Czech structured e-invoice, batteries, installation, commissioning, metering, and handover.
Direct answer
Quickest Solar CRM is our first proposal-first trial for a Czech solar team. QuickEstimate publishes this ranking and sells Quickest. CZK quotations, Czech VAT, Czech structured e-invoice, EDC, distribution-company connection, export-sale and legacy-settlement terms, authorised electrical work, batteries, Czech documents, GDPR processor and transfer terms, Czechia support, local payments, accounting, integrations, installation, testing, commissioning, metering, and handover are all unverified for Quickest.
7 jobs, 7 picks
A useful shortlist starts with the sales or delivery bottleneck. Each winner below reflects a different buying priority, while the overall ranking rewards a CRM that a solar sales team can adopt quickly.

We saved English and Czech searches across Google, Bing, and DuckDuckGo. The accessible results were blocked, thin, or irrelevant, so we do not invent organic positions or questions. The bounded Grok stage returned no completed X evidence report. We assessed vendor pages against the Energy Regulatory Office, CEZ Distribuce, the Electricity Data Centre, the Czech Financial Administration, the Technical Inspection of the Czech Republic, the Office for Personal Data Protection, the Czech Trade Inspection Authority, and the public procurement portal.
Can the product carry system details, proposal status, project milestones, and the delivery handoff without rebuilding the process in custom fields?
Can managers route leads, track activity, automate follow-up, forecast revenue, and see why an opportunity stalled?
Can a rep move from site information to a credible customer proposal, and how much specialist solar design happens inside the platform?
Does the workflow support the language, currency, tax, communications, documents, and handoffs common in Czechia?
What setup, migration, training, administration, and extra software does the apparent subscription require?

Country research
The test is whether accepted sales data survives design, distribution-company review, installation, testing, commissioning, EDC and meter handoffs, export setup, invoicing, and customer handover. One generic approval stage cannot represent those responsibilities.
The Energy Regulatory Office regulates Czech energy markets, while the distribution company serving the site controls its connection process. The CRM should identify the territory, metering point, application route, capacity, design files, technical conditions, estimate, communications, acceptance, work completion, meter status, and later changes. A pipeline label does not prove a successful submission.
Energy Regulatory Office: Energy Regulatory Office ↗CEZ Distribuce publishes dedicated information for electricity producers, but it is only one distribution territory. An installer must follow the actual network operator's current forms and technical terms. Software should preserve submitted versions, equipment and protection data, single-line diagrams, requests for correction, conditions, responsible users, deadlines, approvals, installation changes, commissioning, and meter evidence.
CEZ Distribuce: Information for electricity producers ↗The Electricity Data Centre supports Czech electricity-data services and energy-sharing processes. A CRM does not replace EDC. Where sharing applies, store the EAN or metering identifiers, participants, authority, group or allocation information, effective dates, submissions, validation errors, status, and later changes. Require a live demonstration before accepting any claimed EDC integration.
Elektroenergeticke datove centrum: Electricity Data Centre ↗The Financial Administration identifies 21 percent as the standard Czech VAT rate. Solar jobs may contain equipment, installation, battery, monitoring, service, repair, finance, and building work whose treatment depends on the facts. Configure line-level tax and effective dates, then have a Czech adviser approve any reduced rate, deposits, milestones, corrections, credit notes, cross-border purchases, and reporting.
Financial Administration of the Czech Republic: Value added tax ↗Electrical work, inspection, and reserved technical equipment require qualified responsibility under Czech rules. The Technical Inspection of the Czech Republic is an official reference point. Preserve the accepted design, responsible contractor and people, equipment, protection settings, inspection and test reports, revisions, commissioning, distribution-company conditions, metering, photographs, warranties, manuals, and signed handover.
Technicka inspekce Ceske republiky: Technical Inspection of the Czech Republic ↗Czech solar records contain identity data, addresses, property photographs, electricity use, signatures, finance information, messages, and employee activity. GDPR procurement should cover controller and processor roles, Article 28 terms, subprocessors, security, incidents, storage and support locations, transfers, retention, deletion, access, correction, objection, marketing suppression, and complete export.
Office for Personal Data Protection: Data protection authority ↗The Czech Trade Inspection Authority provides consumer information and receives relevant complaints. The sales record should preserve the channel, quotation, terms, pre-contract information, withdrawal material where applicable, delivery timestamps, signatures, deposits, changes, complaints, and later communication. Czech counsel should approve the installer's actual flow and document versions.
Czech Trade Inspection Authority: Information for consumers ↗Electronic invoicing requirements depend on the customer and transaction. The Czech public-procurement portal documents electronic invoicing for covered procurement. Test recipient identifiers, the required structured format, validation, transport, delivery response, rejection, correction, credit note, attachments, retention, accounting reconciliation, permissions, and export. An emailed PDF is not proof of structured exchange.

Each review explains the useful workflow, the buyer who should shortlist it, and the country-specific question that a sales demo must answer.
Quickest is our first proposal-first trial only if every Czech quotation, grid, tax, privacy, integration, field, and handover gate passes before live use.
Quickest focuses on solar leads, proposals, follow-up, and pipeline visibility. Its public free plan supports a contained adoption test, which is why it ranks first under this guide's declared proposal-first method. That position reflects the method and the publisher's product relationship, not verified Czech breadth.
Every local capability remains unverified: CZK quotations; Czech VAT; buyer-required structured e-invoices; Czech distribution-company and EDC work; authorised electrical-contractor and inspection records; export-sale and legacy-settlement terms; batteries; Czech documents; GDPR processor and transfer terms; Czechia support; local payments, accounting, and integrations; installation, testing, commissioning, metering, and handover. The public security page states AWS Mumbai hosting, which also requires a Czech privacy and transfer review.
Choose it if: proposal and follow-up adoption is the immediate bottleneck and all Czech acceptance gates pass. Choose another platform if: you need evidenced local design, fiscal localisation, or delivery breadth with less verification work.
Arka360 combines solar design and CRM globally, while current Czech grid and export, tax, privacy, and delivery depth still need proof.
Arka360's public product joins AI-assisted 3D design, shading and performance modelling, proposals, CRM, leads, tasks, and project progress. Its public pages describe proposal configuration and residential and commercial use. Czech distribution-company, EDC, export-sale, and electrical documents, VAT, Czech structured e-invoice, GDPR, Czech document quality, WhatsApp, local accounting, field evidence, commissioning, meter work, and handover remain unverified. Omit its outcome figures unless your evaluation substantiates them.
Choose it if: you want to test a global combination of solar design, proposals, and CRM in this shortlist. Choose another platform if: ERP operations matter more than specialist solar design, or you need a free core product.
SurgePV is a credible design and electrical candidate, but its unverified Czech grid and export localisation requires a complete proof.
SurgePV joins roof modelling, shading, simulation, electrical documents, financial modelling, and proposals. No checked page verifies CZK, Czech export terms, distribution-company work, or a EDC API. Require a complete Czech demonstration and reject unsupported outcome claims.
Choose it if: design, electrical documentation, simulation, and proposals are central and current Czech grid and export checks pass. Choose another platform if: you need documented local fiscal support or want less localisation work during evaluation.
OpenSolar is the most accessible design-led option, with every Czech grid, tax, privacy, language, and delivery requirement still needing proof.
OpenSolar keeps site data, design, equipment, production assumptions, price, proposals, and internal project workflow together. The core app remains free, while API Access and supported connectors cost extra. Czech climate or tariff settings, grid connection, EDC, metering, and export-sale terms, VAT, Czech structured e-invoice, Czech documents, GDPR, WhatsApp, local support, commissioning, meter, and handover work remain unverified.
Choose it if: free core design and proposals are the priority and the team can define its surrounding Czech stack. Choose another platform if: you require verified local invoicing or a current grid workflow with less configuration.
Pylon suits project-priced design evaluation, provided Czech assumptions, currency, grid work, privacy, integrations, and delivery evidence pass.
Pylon publishes solar design, interval-data analysis, web and PDF proposals, project tools, API capability, and optional CRM. Its dollar symbol is not clearly Czech currency. Request CZK terms and total cost. Grid connection, EDC, metering, export-sale terms, connection review, export credit, VAT, structured e-invoices, GDPR, bilingual output, WhatsApp, commissioning, and handover remain unverified.
Choose it if: you want project-priced design and proposals with the option to add a connected solar CRM. Choose another platform if: you need broader operations in one implementation or fiscal scope that your adviser has already approved.
Zoho is a capable generic CRM and WhatsApp candidate when the installer has clear ownership for solar design, grid, finance, and field configuration.
Zoho CRM covers leads, deals, activities, email, automation, reports, mobile apps, custom fields, and a documented WhatsApp Business connection. It needs connected solar design and configured CZK quotations, grid and export, technical-study flags, VAT, Czech structured e-invoice, installation, and handover. Test Meta requirements, templates, opt-in, charges, assignment, attachments, retention, suppression, and export.
Choose it if: your team values a mature configurable CRM and can own the Czech solar implementation and integrations. Choose another platform if: you want solar design built in or a system whose Czech fiscal scope has already been demonstrated.
Odoo offers broad operational scope, but Czech fiscal work, solar design, and current grid and export delivery all require a complete demonstration.
Odoo's suite spans CRM, sales, projects, field service, inventory, invoicing, accounting, documents, and signatures. We did not find a working current Czech localisation page during this review. Treat Czech VAT, bookkeeping, structured invoices, retention, audit, and export as unverified until a partner demonstrates the purchased setup. Odoo still needs specialist solar design and configured EDC, qualified electrical-contractor, bilingual, WhatsApp, commissioning, meter, and handover work.
Choose it if: broad operational control outweighs the need for native solar design and you can validate the Czech implementation. Choose another platform if: you need a focused sales trial, a faster design tool, or a lighter implementation.
Buyer guide
Choose by the most expensive broken handoff, then test that handoff using real opportunities, real users, and the documents your customers actually receive.
Quickest tests adoption of a focused lead, quotation, follow-up, and pipeline tool. OpenSolar tests free core design and proposals. Use the same home project, then prove CZK, grid and export, VAT, GDPR, bilingual documents, WhatsApp, and handover.
Quickest is the proposal-first adoption candidate. Arka360 is a global design and CRM candidate, but no Czechia-specific page or localisation proof was found. Neither should pass procurement without the complete current Czech grid and export and data test.
Both position design and proposals for larger projects. Test load data, equipment, simulation, drawings, economics, decision-makers, larger-system grid review, revisions, commissioning, and handover. Neither vendor has verified Czech grid, export, tax, or handover localisation.
OpenSolar offers a free internal core, while Pylon publishes project prices and an optional CRM. Price API, connectors, accounting, support, and users. Inspect how accepted design data reaches grid and export administration and field delivery.
Zoho is the generic CRM candidate for teams that value configurable pipelines, automation, mobile work, and documented WhatsApp Business integration. It needs a specialist design layer and deliberate grid and export, VAT, Czech structured e-invoice, installation, and handover configuration.
Odoo covers CRM, sales, projects, field service, inventory, invoicing, and accounting, but we did not verify a current Czech localisation page. Require the implementation partner to demonstrate VAT, bookkeeping, structured invoices, audit, and export in the purchased version. Add specialist design and build the grid and export workflow with an accountable partner.
Run the same three opportunities in every shortlisted CRM: one ordinary lead, one revision-heavy project, and one deal that already failed. This removes demo theatre and exposes repeated entry, stale documents, weak mobile adoption, and missing local support.
Capture a real lead, assign it, create the proposal, schedule follow-up, record acceptance, and hand it to delivery.
Change the system, equipment, price, payment route, and installation date. Identify every stale record.
Use a duplicate, missed follow-up, rejected proposal, or delayed job and ask the CRM to show what happens next.
Create a Czech koruna quotation with consistent CZK display, line-level tax, deposits, milestones, finance or leasing, discounts, exclusions, validity, and revisions. State the consumption source, system size, production method, degradation, self-consumption, export, tariff source, rate, checked date, and sensitivity. Test domestic and non-domestic templates separately.
Build outright-purchase, service, mixed-item, staged-payment, cancellation, credit-note, and debit-note samples. Confirm who sets VAT classifications, which system issues the invoice, what structured data a covered buyer requires, how delivery and rejection statuses return, and how accounting reconciles it. Obtain current Czech tax and electronic-invoice advice.
Record grid and export for new 2026 work, distribution company data, EDC reference, qualified electrical contractor identity, customer, metering-point, distribution-company, supplier, and export-buyer details, capacity, documents, submission version, queries, responses, approval, expiry, and owner. Require a live demonstration before treating a link or compliance label as EDC submission. Keep legacy support and settlement groups only for historical cases.
Test a small home system, a battery system, a larger commercial connection, and a project with distribution-company conditions. Store the application, metering-point data, capacity, equipment, drawings, protection settings, communications, costs, conditions, approval, changes, and commissioning. Use current distribution-company rules and leave technical decisions to authorised people.
Residential work needs household contacts, bill and roof data, domestic export assumptions, financing, appointment, and customer communications. Commercial work can require site and billing entities, maximum demand, load profiles, procurement stages, lease or PPA terms, technical studies, approvals, multiple decision-makers, and staged delivery. Test separate pipelines with common reporting and make sure a site, account, opportunity, contract, and installation are not collapsed into one record.
Create the proposal, selected customer messages, consent notice, form labels, terms, and handover checklist in English and Czech, then have a fluent reviewer assess both versions. Test Czech names, addresses, phone numbers, dates, fonts, and CZK values. For WhatsApp, confirm the approved channel, templates, opt-in evidence, conversation ownership, attachments, suppression, retention, and export. Field users should complete core work on phones with weak connectivity considered.
Collect the vendor privacy notice, processing terms, security measures, current subprocessors, hosting and backup locations, support-access countries, incident commitments, cross-border transfer position, retention schedule, deletion process, and usable export. Run a customer access and correction request, consent withdrawal, marketing suppression, staff permission change, account closure, and deletion request. Document the installer's own purposes and retention rules instead of copying vendor language unchanged.
Map the exact systems used for bank transfer, cards, finance, accounting, inventory, email, calendar, telephony, signature, design, and reporting. Verify Czech availability, currency, fees, tax fields, sync direction, duplicate handling, error alerts, retries, permissions, and exit export. Obtain local or regional support hours, languages, response routes, implementation scope, data-migration responsibility, and escalation terms in writing.
A field user should receive the accepted scope and latest drawing, complete the site survey, record equipment and serial numbers, attach photographs, log deviations, capture the single-line diagram, test results, testing and commissioning form, competent-person and contractor records, defects, meter status, distribution-company, supplier, and EDC correspondence, commencement information, warranties, manuals, customer training, and signed handover. Approved files must remain versioned and exportable.
Import duplicate leads, bilingual contacts, multi-site customers, historical settlement cases, open grid-connection jobs, quotations, documents, consent, tax fields, and invoice references. Test roles for sales, design, grid administration, field, finance, management, and contractors. Inspect changes to prices, assumptions, documents, customer details, and status. Export records, attachments, messages, history, and configuration.
The real budget
The shortlist mixes Indian rupees, US dollars, unqualified dollar symbols, per-project charges, free internal products, and custom quotes. Do not convert these into a single CZK table and imply Czech contracts, taxes, support, or payment methods that have not been verified.
India-facing public pricing. Pro requires at least three users. Czech terms are unverified.
No public Czech list price found. Request CZK billing and full implementation terms.
Seat conditions apply. Individual plan is $1,899/user/year. Confirm currency and Czechia terms.
External API Access became paid from 16 April 2026; supported connectors are billed separately.
Quickest publishes Free with 10 proposals per month for one user and Pro at ₹6,999 per user per year with a minimum of three users. These are India-facing public terms. No verified CZK price, Czech VAT treatment, contract entity, payment route, local support commitment, or Czechia data terms were found. Obtain a written quotation and complete security review.
Arka360 has no public Czech list price on the checked pages. Request CZK billing, limits, imagery, onboarding, migration, support, integrations, taxes, renewal, and exit costs. SurgePV publishes annual per-user prices in dollars: $1,899 for an individual plan and displayed team tiers at $1,499 and $1,299, subject to seat conditions. Confirm currency and Czechia terms.
OpenSolar says its core app remains free for end-to-end internal work. API Access became paid from 16 April 2026, and supported connectors follow separate billing. A stack that sends data to an external CRM or accounting product therefore needs a written connectivity estimate. Pylon displays $4 for a Standard project, $10 for a Pro project, and $49 per user per month for Solar CRM. The checked page does not clearly label those dollars as CZK.
Zoho CRM's global page displays Free for three users, Standard at US$14, Professional at US$23, and Enterprise at US$40 per user per month. Confirm billing basis, Czech currency, tax, WhatsApp charges, storage, implementation, and app costs. Odoo offers One App Free and paid all-app plans. Obtain a Czechia quote for hosting, users, localisation, implementation, custom work, support, and maintenance.
Our number-one pick
Quickest ranks first because this comparison gives the most weight to proposal-first value and adoption. A focused lead, quotation, follow-up, and pipeline path may be easier for a small seller to trial. The free plan shows whether staff keep records current.
The recommendation is conditional and commercially disclosed. QuickEstimate publishes this guide and sells Quickest. We found no public proof of CZK quotations, Czech VAT, Czech structured e-invoice, EDC integration, distribution-company connection, authorised electrical records, supplier export terms, legacy support and settlements, battery assumptions, Czech documents, GDPR processor and transfer terms, Czechia support, local accounting or integrations, installation, testing, commissioning, metering, or handover.
Quickest uses rupee pricing and says customer data is hosted in AWS Mumbai. Review the contracting entity, processor terms, subprocessors, storage and backup regions, support access, cross-border transfers, security, incidents, retention, deletion, and export before uploading customer information.
OpenSolar is the better evidenced choice when accessible solar design and proposals matter most. Odoo is the broad operations candidate, but its Czech localisation is unverified. SurgePV, OpenSolar, and Pylon deserve design-led trials, while Zoho suits teams ready to configure a generic CRM and connect several specialist systems.
Run a home system, a battery case, and a larger commercial connection. Use real sales, design, grid, field, finance, and management users. Record corrections, duplicate entry, stale versions, missed tasks, mobile friction, integration errors, and support. Quickest earns rollout only when every local gate passes.
Your next move
Start with Quickest and the specialist closest to your largest local requirement. Use the same evidence and test deals for both.
Name the bottleneck. Pick lead response, proposal speed, design, payment, install handoff, or management visibility.
Choose two tools. Compare Quickest with the strongest specialist for that bottleneck.
Run the Three-Deal Proof. Score adoption, repeated entry, revision handling, support, and full annual cost.

Common questions
Quickest is our first proposal-first adoption trial. QuickEstimate publishes this ranking and sells Quickest. All Czech localisation remains unverified. OpenSolar is the accessible design-led alternative. Odoo is a broad ERP candidate whose Czech fiscal scope is also unverified. The right rollout depends on CZK, VAT, distribution-company, EDC, export, GDPR, Czech document, accounting, field, battery, and handover tests.
Do not assume one nationwide rate in a proposal. Identify the relevant distribution company, metering arrangement, electricity supplier or export buyer, and the current purchase contract. Keep any legacy support and settlement group on the existing installation record. Date every import price, export price, tax, fee, contract term, production, consumption, self-use, and battery assumption, then show sensitivity instead of guaranteed savings.
EDC supports Czech electricity-data services and energy-sharing processes. It is not a generic installer CRM portal, and the relevant distribution company and market parties own different steps. Ask a vendor to demonstrate any claimed connection and name the fields, statuses, permissions, and errors exchanged. Otherwise use the CRM to control approved source data, documents, owners, references, queries, meter status, export contract, and evidence of completion.
The Czech Financial Administration identifies 21 percent as the standard VAT rate, but a mixed project can contain equipment, installation, service, repair, finance, and commercial items that require proper analysis. Use line-level codes, effective dates, deposits, milestones, corrections, and credit notes. Have a Czech adviser approve the actual classifications, invoice wording, cross-border purchases, and reporting before the setup goes live.
Not when the buyer requires structured electronic delivery. Test the recipient identifier, buyer-required format, validation, delivery response, attachments, rejection, correction, credit note, accounting reconciliation, retention, and audit history for the actual route. Verify the purchased software version and implementation. A quotation PDF or emailed invoice does not prove successful structured delivery.
Request Article 28 processor terms, security measures, subprocessors, storage and backup regions, support-access countries, transfer safeguards, incident terms, retention, deletion, and export. Test customer access, correction, objection, consent withdrawal, marketing suppression, permissions, and closure. Quickest states AWS Mumbai hosting, so the buyer must assess international transfers and every connected messaging, signature, analytics, support, and backup service.
Preserve the accepted design, distribution-company conditions, equipment and serial numbers, inverter and battery settings, single-line diagram, authorised company and responsible people, inspection and test evidence, photographs, deviations, commissioning, meter exchange or configuration, export setup, warranties, manuals, customer instruction, defects, and signed handover. Keep approved versions immutable to ordinary users and include attachments and history in the exit export.
Run a home system, a battery case, and a commercial project through real sales, design, office, field, and finance users. Complete CZK quotation, VAT, contract, distribution-company handoff, EDC and meter references, export assumptions, installation, commissioning, Czech structured e-invoice or accounting exchange, and handover. Record corrections, duplicate entry, stale documents, missed tasks, mobile friction, integration errors, support answers, and total contract cost.
Use the Three-Deal Proof and require every vendor to show the same lead, revision, document, and failed handoff.
