Solar design and proposals for grid, hybrid, off-grid and utility-scale systems

This tool is for solar and electrical engineers. It sizes systems that get built, and prices proposals that get issued. What it produces depends on the parameters chosen for it — the weather dataset, the module and inverter data, the losses, the tariff, the site conditions. Choose those wrongly and the tool will give you a confident answer that is wrong, with no indication that anything is amiss. Judging whether the inputs and the results are right is the operator's job, and it is not work for someone who is not well versed in solar design. Accounts are reviewed before they are released.

Your organisation and plan

You become your organisation's administrator and can add up to two colleagues. Every registration is reviewed before it can be used. Whichever plan you choose, the first 60 days are free from approval, or until 5 projects are completed, whichever comes first; then pay monthly or annually.

An administrator reads this to decide whether to release the account, so it is worth being specific.

What will you use this tool for?

Declaration

Each of these is confirmed separately. Your acceptance is recorded with the date and the version of this wording.

I am a solar or electrical engineer, or work under the supervision of one, and I am competent to judge whether the inputs and results of a design are correct. I understand that what this tool produces depends on the parameters chosen for it - the resource dataset, module and inverter data, losses, tariff and site conditions - and that choosing them wrongly produces a confident answer that is wrong. I understand that a design from this tool is preliminary until an engineer has reviewed and approved it, and that I must not issue one to a customer as final without that review. I am authorised by my organisation to use this tool, and I will not share my account or use it for any purpose other than professional solar design work. I agree to the Terms of Use and have read the Privacy notice.
