Solar PPA | Commercial Solar Power Purchase Agreement

Power Purchase Agreement For Solar

A Power Purchase Agreement For Solar is a long-term contract to purchase the electricity that is generated by these solar PPA panels installed on your premises. This arrangement is made between a retailer (or generator) and a purchaser (or off-taker) for the purchase of electricity. Electricity is generated by the PV system and is charged at a kWh rate for the total production of electricity by the consoles or by the site consumption. This is known as either a Production or a Consumption Solar PPA. The arrangement is typically between 7 to 30 years and usually has an annual price increase for the duration of the term. This consensus has no upfront cost, however, the purchaser needs to buy the kWh as agreed in the PPA agreement.

Are Solar PPA worth it?

The major benefit of a solar PPA agreement is that you get a guaranteed low rate for electricity – with zero capital outlay. You also have zero operational risk as the responsibility for maintaining and servicing the renewable system is borne by the provider. This renewable system installed at your premises will be owned by the provider until the end of the solar PPA term when ownership transfers to your business.

Essentially, a solar PPA is a contract between your business and the provider to purchase renewable energy at a rate that is lower than buying it from the main electricity grid.

A power purchase agreement for solar is a great way to lock in a predictable, guaranteed low rate for electricity over a long period – typically 10-20 years.

How does a Solar PPA work?

It’s important to be aware that this arrangement covers your electricity costs for daytime power usage only. When the sun goes down, your business will have to purchase electricity from the grid – this will not be at the same low rate as the arrangement.

The rate for night-time grid electricity can be negotiated on your behalf by the provider, or directly with the electricity retailer of your choice.

How long are Solar PPAs for?

The term length of most commercial solar PPAs ranges from 7 years to 30 years. However, both shorter and longer terms for this arrangement can be negotiated, depending on your business requirements.

How to get a solar PPA that’s right for your business

There are a few potential pitfalls to avoid when negotiating a power purchase agreement for solar to your business.
Here’s a summary of what to watch out:

What to negotiate forWhat to avoid
Own system outright at end of the arrangement period – without any additional paymentsBalloon payment – i.e. a final payment at the end of the arrangement term. It’s like paying for the system twice.
Insist on a consumption-based pricing structure – not a production-based structure.

Consumption-based means paying only for the renewable energy you use in your business. This puts the onus on the provider not to oversize the system.

  • Consumption-based means paying only for the renewable energy you use in your business. This puts the onus on the provider not to oversize the system.
Production-based PPA pricing structure

  • This is where your business pays for all renewable energy generated regardless of whether it’s used in the business.

  • With this pricing structure, there’s a risk that the solar PPA provider may install more than what you need.
Fixed price or CPI linked

  • If guaranteed locked in energy pricing is important, ask for a fixed price arrangement
CPI linked

  • Exposes the business to the risk of inflation
Term of Solar PPA

  • Solar PPA terms are not set in stone. Negotiate the term of term arrangement that suits your business.

  • A shorter term (say 3-5 years) will reduce upfront savings, but you’ll own the system quicker
Don’t accept a PPA term that doesn’t fit your business

  • No need to accept a 20 or 30 year term if that’s not right for your business

  • However, longer arrangements generally come with lower price per kilowatt hour and mean you don’t have to worry about system maintenance

Solar PPAs Versus Getting A Lease

There are many similarities between solar PPA agreement and leases; basically they are just different forms of financing.

The main differences are:


With this lease, you pay a flat monthly fee for the renewable system which should be less than what you were paying on your monthly electricity bills. For example, if your business was paying $2,000 a month for electricity, you’d be looking for a lease that was less than $2,000.

In contrast, with a solar PPA you pay a guaranteed price per kilowatt of electricity produced by your PPA solar panels (although you can sometimes negotiate these arrangements where the price you pay per kilowatt hour is based on consumption, not production). This price will be lower than the price per kilowatt hour you pay for grid electricity. For example, if you pay 20 cents per kilowatt hour for grid electricity, the overall consensus should be for less than this amount.


Another difference between solar PPAs and leases is their duration. These leases can be as short as 3-5 years, whereas a consensus typically last at least 10 years in duration, sometimes as long as 30 years.
