Solar Business Plan Template for a New Installer (Fill-In)

A solar business plan for a new installer does not need forty pages. It needs nine tables you can fill in over a few sittings, and the honesty to leave a cell open when you do not know the number yet.

This post is that document. Other guides on this site cover the pieces: how to start a solar EPC business, how much start-up capital to set aside and which revenue models work. Here is the plan that holds them together, with a place for your own numbers in every table.

Two things are different from most templates. Every line carries a mark that says whether it is a dated fact from an official page, a guess you made, or something still open. And the cash table comes with a stressed run, so you see the month your money runs out before you spend any.

Nothing below is a forecast or a promise of what you will earn. The worked numbers are made up to show the arithmetic. Replace them.

How to fill in this plan: the Fact-Guess-Open marks

The Fact-Guess-Open rule says every line in your plan carries exactly one mark, F, G or O, and no line may be left unmarked. It keeps a plan honest because a guess can never pass as a fact.

At each review, every O must become an F or a G, and every G should move toward an F as real jobs arrive. A plan with many O marks is not a bad plan on day one. A plan with many G marks on day 90 is. The nine tables follow in the order you will use them. Hindi readers can start with this Roman Hindi start-up guide and come back here for the tables.

Table 1: Market and territory

The official numbers show large demand and many installers. PIB reported 51.58 lakh households benefiting under PM Surya Ghar as of 12 August 2026, and an earlier PIB release said 34,219 vendors were registered, 29,469 of them active, as of 4 August 2026. Your plan needs a reason a customer picks you.

Treat these as context, not a forecast. The Union Minister said in June 2026 that he hopes to cross 75 lakh households by December 2026. A hope is not a sales target for your district. The guidelines also say the scheme is implemented till FY 2026-27, so a year-two plan that depends on it needs an O mark until you see an official extension.

The central assistance applies only to residential consumers. The guidelines say no CFA is given to commercial and industrial customers, so a factory customer's economics are different. Housing societies sit in between, with their own CFA rate for common facilities.

Table 2: Services and pricing approach

For a home customer, the scheme fixes the subsidy and leaves the price to you and the customer. The CFA is ₹30,000 per kW for the first 2 kW and ₹18,000 for the third kW, capped at ₹78,000, and the guidelines say the consumer is free to enter into arrangements with any registered vendor at mutually decided rates (clause 6(c)).

The "benchmark cost" of ₹50,000 per kW (first 2 kW) and ₹45,000 (additional kW) is the figure the CFA is calculated on. It is not a price cap and not a price you must charge.

Build every price from the bottom. In the worked example used across this guide, an all-in ₹1,95,000 quote for a 3 kW home system is made of ₹1,47,000 of materials, ₹15,000 of labour, ₹6,000 of paperwork and commissioning, ₹8,000 as a five-year service reserve, and ₹19,000 left for margin. Those lines come from the illustrative table in why solar prices vary, and they are assumptions.

GST on renewable energy devices was cut from 12% to 5% from 22 September 2025, according to PIB, 17 September 2025. For the service part of a supply-and-install contract (30% of the value under the 70:30 rule), serial number 38 of Notification 11/2017-Central Tax (Rate) reads 9% central tax and the integrated tax entry reads 18% (Notification 27/2018-Central Tax (Rate), CBIC tax portal, 31 October 2026). State tax follows each State's own notification, which we did not open, so the service-rate cell stays O until your CA confirms your contract's classification. Read GST on solar installation service with your CA. When module prices move, use the routine in solar price list update so no rep quotes an old rate.

Table 3: Registrations and compliance checklist

A new installer needs five things on paper: a legal entity, Udyam, GST, PM Surya Ghar vendor registration and a state electrical contractor licence. The scheme runs only through vendors registered on the National Portal, so vendor registration decides whether you can take subsidy-linked home jobs.

Bank guarantee for national registration: the MNRE vendor manual of 26 June 2024 shows ₹25 lakh for a national vendor, or ₹2.5 lakh per state up to ₹25 lakh for multi-state, with the hard copy posted to REC in Gurugram. State-level registration is run by the state, so its terms sit in your state's own notice, not here.

Here is what one state asks, to show the kind of detail to look for. The Tamil Nadu Electrical Licensing Board's own Form A instructions for a Grade A contractor licence (the sheet itself calls it the "EA" licence, which covers high-voltage work) say the fee has been ₹30,000 from 1 January 2024, the owner must be at least 25 with class VIII passed, and the applicant must employ one qualified supervisor and two wiremen full time. They also list seven test instruments, to be tested at a government laboratory within 3 months before applying, and a bank solvency certificate of ₹50,000 valid for three years.

That is one board. We could not open the licensing pages of other states from our connection, so we give no other state's fee. Ask yours the same questions: who issues it, which class, what staff, what instruments, what fee, how long it stays valid. For the wider licence map, see the solar business licence guide.

Table 4: Team plan

Plan roles before names. The first hires follow the licence and the work, not the other way round. For each role, set a hire trigger as a count of jobs, not a feeling.

Write the trigger before you need the person, because a first hire made in panic usually costs a month of cash. Hiring and first-month routines are in how to hire a solar sales rep and the first 30 days of a new rep.

One more fact belongs in this table. MNRE's vendor rating framework gives a rating only after a vendor has installed at least 50 eligible systems, so in year one you will likely have no star rating. Your first reviews and your handover quality carry the weight.

Table 5: Lead plan

Plan leads backwards from jobs: jobs wanted, divided by the share of proposals that sign, gives the proposals you must send. The share is a guess until you have sent about 30 proposals, so mark it G and test it.

The last row comes from MNRE's installer manual of 29 June 2024, whose vendor menu shows a list of consumers who expressed interest. Whatever the channel, write the source on every lead the day it arrives. Solar lead source attribution shows how, and monthly sales targets extends the back-solve to a rep.

Table 6: Twelve-month unit economics and cash

The cash table is arithmetic on assumptions, not a forecast and not what any installer earns. List the assumptions first, then run the months twice. In this example the planned run stays positive and the stressed run goes below zero in month 8.

All figures are in ₹ thousand. Month 1 carries the one-time set-up. Cash out includes materials, labour, the service reserve and fixed costs.

Read three things. The planned run bottoms out at ₹1.15 lakh in month 7, the month the optional software payment lands. The monthly net turns positive in month 8. And the year as a whole uses cash, because 31 jobs at ₹19,000 earn ₹5.89 lakh against about ₹7.95 lakh of fixed and set-up cost, with four jobs still being collected at month 12.

The Dry-Month Test has four steps.

1. 1

   Run the planned months

   Fill the table from your own assumptions. Note the lowest closing cash and its month.

2. 2

   Run the stress

   Cut your signings sharply (here 18 jobs instead of 31) and let every last payment arrive two months late. Note the first month closing cash goes below zero. That is your dry month.

3. 3

   Name the gap

   In this example the stressed run ends month 12 at minus ₹0.77 lakh, so it needs about ₹77,000 more, plus a buffer.

4. 4

   Close the gap on paper

   Cut a fixed cost, raise the advance you ask for, or arrange funding. Re-run and confirm the dry month is gone.

In the example, a founder draw of ₹15,000 instead of ₹25,000 keeps the stressed run above zero, with a low of ₹39,000 in month 10. Cutting a cost is the easiest lever to pull. Raising price is harder, because it can cost you jobs. Jobs a month cover running costs when jobs times margin reaches fixed cost. Rounding up to whole jobs hides how much a small change matters, which is why the Dry-Month Test beats a break-even number. For the week-by-week view once you are trading, use the 13-week table in cash flow for solar EPCs, and set payment pegs with payment terms for solar customers. For the revenue side beyond installs, see solar business revenue models.

Table 7: Funding options

Fill this table after the Dry-Month Test, so you borrow a number you can name. Each row is read from a Ministry of MSME document or a PIB release, because the scheme sites (kviconline, mudra.org.in, cgtmse.in) did not open for us. Whether your solar installation activity qualifies is for the bank or district agency to confirm.

One loan in this story is not yours. PIB says concessional home-solar loans at 5.75% for the present, over 10 years are for the household. It helps your customer afford the job, and it changes how fast the balance reaches you. See solar business loan options for a wider lender map.

Table 8: Risks

A risk row is only useful if it names an early sign and a cap. Write the owner, because a risk with no owner is just a worry.

Table 9: The 90-day launch checklist

Ninety days is enough to register, price, run a pilot and review honestly. Tick a row only when the proof exists, and turn each O into an F or a G at the review.

How QuickEstimate fits

This plan asks for proposals early, and Quickest Solar CRM lets you start without paying. The Free plan has 1 user and 10 proposals a month, with no card. In the lead example above, 12 proposals a month is already past 10, so that is the month to decide on Pro.

Quickest Solar CRM lets you build branded proposals with your logo, items, product photos and terms, apply the PM Surya Ghar subsidy inside the proposal and share the PDF on WhatsApp. You can also add and edit leads, use labels and follow-up reminders, filter leads, set your own lead stages, and read a dashboard and team report at your monthly review.

Pro costs ₹6,999 per user per year, with a 3-user minimum (₹20,997 for 3 users), billed yearly with a GST invoice. QuickEstimate is built and supported in Surat.

What to do this week

1. Copy the nine tables into one document and put an F, G or O on every line you can already fill.
2. Replace the example numbers in the cash table with your own, then run the stressed months and write down your dry month.
3. Book your CA, send your questions to your state licensing board, and start Udyam. Those three cost little and take the longest to answer.

Frequently asked questions

What should a solar business plan for a new installer include?

It should cover nine things: your territory, the services and prices you will offer, the registrations you need, your team, your lead plan, a 12-month cash table, how you will fund the gap, your main risks, and a 90-day launch checklist. Mark each line as a dated fact, your own guess, or an open question, so you can see what the plan really rests on.

How much money does a new solar installer need to start?

It depends on your state, your licence, how many jobs you run at once and what suppliers allow. The example on this page opens with an assumed ₹5 lakh of own money, which is a guess, not a recommendation. The separate start-up capital guide breaks the amount into licensing, tools, working capital and running costs.

Which registrations does a new installer need before the first job?

For subsidy work, PM Surya Ghar runs only through vendors registered on its National Portal, per MNRE's July 2025 guidelines. Udyam is free, according to the Udyam portal. GST depends on turnover and how your supply is classified, so ask a CA. Electrical contractor licences are issued state by state, so read your own licensing board's current form.

How many jobs a month does a small installer need to break even?

Divide your monthly fixed cost by the margin per job. In the worked example, ₹52,000 of fixed cost against ₹19,000 of margin per job means three jobs a month cover running costs. Those numbers are assumptions made for the example. Use your own quotes and your own costs before you rely on any break-even figure.

Can a new solar installer get a loan or a subsidy for the business?

Several schemes exist, but each lender or agency decides. PMEGP gives a margin-money subsidy on a bank loan, Mudra loans go up to ₹20 lakh, and CGTMSE backs loans so lenders can lend to micro and small enterprises without collateral. Whether a solar installation activity qualifies is for the bank or the district agency to confirm, so ask before you build the plan around it.

Is PM Surya Ghar demand still growing for installers?

PIB reported 51.58 lakh households benefiting as of 12 August 2026, against a target of 1 crore. The guidelines say the scheme is implemented till FY 2026-27, and we did not find an official extension. Plan the first year on the scheme, and plan what you sell if it ends or changes.

How often should I update my solar business plan?

Update the cash table every month with real numbers, review the whole plan at day 30, 60 and 90, and re-check every dated fact every six months. Re-check sooner if MNRE amends the guidelines, your state changes its vendor rules, or a lender changes its terms.

Can I use QuickEstimate while I write the plan?

Yes. The Free plan has 1 user and 10 proposals a month, with no card needed. It is enough to test proposals on your first site visits. Pro costs ₹6,999 per user per year with a 3-user minimum, billed yearly with a GST invoice, so ₹20,997 for 3 users.
