How much of your solar quote's savings depends on price rises?

Your quote and your bill

Example numbers to start. Runs in your browser. Nothing is sent.

At your current price, the quote's production is worth $67,500 over 25 years. The quote projects $90,000, so 25% of it depends on other assumptions, such as price rises.

Method: production value = the quote's yearly production x your current price per kWh x the years its savings cover. It assumes no price rises and no degradation, and values every kWh at the price you pay, so it is on the generous side. The difference from the quote's projected savings is what rests on its other assumptions. Loan cost = monthly payment x the term in months, compared with the price after incentives.

The problem

Residential solar is sold door to door and by phone with inflated savings projections, and with long-term financing that can cost more than the system.

Every installer uses different assumptions about production, degradation, electricity price inflation and financing, so quotes cannot be compared, and homeowners sign contracts they do not understand.

Who it is for

  • Homeowners with quotes in hand

    Homeowners considering rooftop solar who have received one or two quotes and cannot evaluate them.

  • High electricity cost markets

    Homeowners in markets where electricity is expensive, weighing up rooftop solar.

What your solar quote actually means

Submit the quotes you have received. Each is modelled honestly on the same basis, with a plain verdict.

  1. Production for your roof

    Expected production for your roof, orientation and shading, from real irradiance data.

  2. Realistic degradation

    Degradation is modelled realistically.

  3. Honest electricity prices

    Honest electricity price assumptions, rather than the inflated ones in the sales projection.

  4. The true cost of financing

    The true cost of the financing, including dealer fees hidden in the cash price.

  5. Like-for-like comparison

    Every quote you submit, compared on the same basis.

  6. A plain verdict

    Including when the answer is that solar does not pay back at this quote or on this roof.

Not unless you ask to be introduced. The analysis comes with no handover of your details to installers, and contact details are never sold.
How is each quote modelled?
On the same basis: expected production for your roof, orientation and shading from real irradiance data, realistic degradation, honest electricity price assumptions, and the true cost of financing including dealer fees hidden in the cash price.
Will it tell me if solar is not worth it?
Yes. The verdict says so plainly when solar does not pay back at this quote or on this roof.

Why should I trust the solar quote calculator?
It is arithmetic on figures from your own quote and bill, worked out in your browser. It uses no tariffs, forecasts or production data of its own, and takes the quote's production figure as given. The free quote analysis models production for your roof and the full cost of financing.
