PV design software for installers and EPCs

Solar design software that works with you like your trusted engineer.

EasySolar AI is an engineer with professional PV design tools at hand. Send a short brief from the office, the client’s kitchen table or the car, and the engineer prepares the system design, the yield and energy balance, the price from your own component list, the proposal and even the email to the client. Nothing goes out on its own: you check it, you approve it, you send it.

Four design methods

Four tools for every PV design. You pick the one that fits, the engineer opens it.

A house outside town, a warehouse, a field for a farm: each site calls for a different tool. You choose the method that fits what you have, an address, a phone photo or a drone shot, and the engineer opens that tool at the project address and lays out the modules. You correct the outline where the imagery is old and confirm the layout. Switch methods at any point; the project keeps the client, the address and the pricing.

01 · Roof photo from the ground

Take a photo from the garden. Modules land in correct perspective

When the aerial image is outdated, the roof is too steep, or the client wants to see the system the way they see it from the garden. Upload a phone photo; the engineer opens the perspective tool, computes the perspective and scales the modules into depth. All you add is the four corners of the roof face and one reference dimension. The client gets a picture of their own house, not a diagram.

02 · Solar farm and industrial

Click the parcel. Tables fall into rows on the orthophoto

Point at the parcel. The engineer opens the farm tool on the orthophoto, takes the parcel outline and lays the tables in rows with correct spacing; the counter runs into thousands of modules. You choose the structure and adjust the areas. Live dimensions on every area, east-west or fixed-tilt, cadastral parcel outlines where the registry is open.

03 · Google Maps, automatic

Type the address. The engineer finds the roof and places the modules

Type the address. The engineer finds the roof, reads each face with its azimuth and pitch, and fills it with modules from your price list. You confirm the layout or fix the outline. The fastest route to a first quote, often while the client is still on the phone, and the tool the engineer opens by default.

04 · Drone image or your own map

Have a better image than the satellite? Work on it

Yesterday’s drone survey, a roof plan from the building permit, a surveyor’s map or a site sketch. Upload the file and mark one known distance; the engineer scales the image and from there works exactly like the automatic method: outline, obstacles, modules, all laid out for you to correct.

Whichever tool the engineer opens, the result lands in the same project: a module layout, a price from your component list, an energy balance, a yield estimate and a proposal from your template. All of it waits for your review before anything reaches the client. Watch the video tutorials.

The EasySolar AI console

One message from the client meeting, the car or your holiday is enough

The console is your design office, with an engineer inside. Send one message about the client and the engineer opens the project, lays out the roof, prices the system from your list, runs the balance and comes back with the proposal and even the email text, with a graphic of the system and a link to the full offer. The engineer sends nothing: you review every piece and decide what goes to the client.

Works with all four design methods
  • Google Maps, automatic
  • Solar farm and industrial
  • Roof photo from the ground
  • Drone image or your own map

Start

One message, from anywhere

From the client’s table, the car or the beach: type the address and say which method fits the site. The engineer opens the right tool, and the steps are the same for a house roof and a 2 MW farm.

No model call

1 · Address

The engineer opens the project

Type the address and confirm the pin. The engineer creates the client and the project and opens the design tool at that address. No “add client”, “add project”, “choose method” across three screens.

Deterministic, no model

2 · Brief

One sentence about the client is enough

Brief the engineer the way you would a colleague: who they are, what they pay for electricity, what they want. Missing values the engineer takes from the client’s previous project, your company defaults or the tariff table, and shows where each one came from, so you can check it.

The model reads, the console saves

3 · Modules

The engineer opens the roof editor. You confirm the layout

Modules land in the editor you already know. Move, add or remove what the roof needs, then “Save and continue”. The engineer waits beside it and knows what you saved.

The EasySolar AI editor, inside the conversation

4 · Complete

Price, balance, yield and proposal, ready for your review

After you save, the engineer runs the valuation, the energy balance and the yield in EasySolar AI and comes back with the proposal and its link. Nothing has gone to the client yet; that part is yours.

Numbers from EasySolar AI only

After completion

Changes sound like talking to a colleague

“Add a 5-year loan.” “Write a summary I can send by email.” The engineer recalculates the financing and comes back with the email: the figures, a graphic of the system and a link to the full offer. You read it, change what you like and send it from your own mailbox. Every tool used is listed in the side panel.

Why it pays off

A fast design office with an engineer you trust. That is how you double conversion.

Set the number of offers you send in a year. If 10% of them turn into sales today and you double your conversion, you install twice as many systems.2 The engineer prepares each proposal in minutes, so every offer goes out while the client is still interested.

Speed decides the deal: a lead contacted within 5 minutes is 21× more likely to qualify than one contacted after 30.1 With the engineer in EasySolar AI you take a client from the first message to a proposal in 5 minutes, and nothing goes out before you have checked it.

  • One message about the client
  • Roof design
  • Yield and energy balance
  • Price from your list
  • Proposal and email
  • Your review. You send.
100
Sales today, at 10% conversion
10
Sales at 2× conversion (20%)
20
Extra installations a year
+10

Whether you send 20 offers a year or 1000, the engineer prepares each one the same way: in minutes, from trusted data, for your review.

1 J. Oldroyd, Lead Response Management Study, MIT Sloan / InsideSales.com, 2007. The figure describes lead response time in the study sample and is not a measurement of EasySolar AI results.

2 Example: a 10% starting conversion doubled to 20%. It shows the arithmetic, not a promise of results; your conversion depends on your market, prices and team.

Where the numbers come from

You talk to the engineer. The engineer works with data and tools you can trust.

The engineer reads your brief and writes the proposal text, but never guesses a number. Every figure comes from the EasySolar AI calculation engine, satellite irradiance data, your component list and your templates, exactly as in the classic view, and you see each one before the client does.

Yield

Production from irradiance, shading and losses

Irradiance from NASA satellite data for the project location. Azimuth and pitch per roof face, horizon and object shading, temperature and system losses, module and inverter data from your database. Annual and monthly production for every variant.

Energy balance

Production matched to real consumption

Model the client’s load profile, size battery storage and see self-consumption and grid exchange before you quote; the same graphic balance goes into the proposal. The same engine powers the free calculators you can embed on your own site.

Poland · Home market

Our home market, which we have been helping shape from the very beginning. With over 22 GW of installed PV capacity and more than 1.5 million prosumers, Poland remains one of Europe's largest rooftop solar markets.

After the design

The engineer even drafts the email to the client. But sends nothing.

Design and calculation are the core. Everything after that the engineer prepares in the same project, so nothing is re-typed: the proposal, the client panel, the schematic, the email. None of it reaches the client until you have read it and pressed send yourself.

Lead generator and response

Leads arrive sized, and get answered in five minutes

Embed the calculator on your website. Every estimate arrives as a qualified lead with roof data, system size and contact details, and EasySolar AI routes it to your best rep with the design already attached. Answering in 5 minutes instead of 30 makes qualifying the lead 21 times more likely.

Questions installers ask

Before you start

Does EasySolar AI send anything to my clients by itself?

No. It prepares the proposal, the email and the documents; you review them and send them from your own account. Nothing leaves without you.

Do I need to configure anything before I start?

No. Tariffs, incentives and metering rules for 15 markets, module and inverter databases and a proposal template are ready on day one, so your first project can start right after signup. Later you can add your own price list and template, and integrations such as Slack, email or your own warehouse.

Can I design ground-mounted systems and solar farms, not just roofs?

Yes. The same PV design software covers roofs and farms: the farm tool lays tables in rows on an orthophoto with correct spacing, east-west or fixed-tilt structures, from 100 kWp to multi-megawatt sites.

Where do the irradiance and yield figures come from?

From the EasySolar AI calculation engine using irradiance data for the project location, roof azimuth and pitch, shading and system losses. The language model never generates a number.

Does it work in my country?

Fifteen markets are preconfigured with tariffs, incentives and metering rules. For any other market you define your own scheme in a few minutes and the interface runs in 25 languages.

Can I use my own module and inverter prices?

Yes. Pricing always comes from your component list and labour rates. Upload it once or sync it from Google Sheets via Zapier.

What happens if the aerial image is old or the building is new?

Switch to the photo method or upload a drone image or roof plan. One reference dimension sets the scale and you continue as usual.

Can the client see the design?

Yes, once you share it. The client receives an interactive proposal by link and a personal panel with documents and project progress.

How does the free trial work?

3 days with full access. A card is required to start and nothing is charged before the trial ends. Cancel in one click from your account.
