How much solar do I need for my house?

Size follows annual consumption, sun hours and shading. A rough method is to divide your annual kilowatt-hours by about 1,450 in South Florida or 1,600 in coastal Southern California, then reduce for shade. Most single-family roofs cap out around 12 kW.

Can I get a solar estimate without a sales call?

Yes. This estimate is produced from six answers and shown on screen. If you choose the email-only option we do not collect a phone number at all.

Q: Can renters get solar?

A lease attaches to the property for around twenty-five years, so it has to be signed by whoever owns the home. Renters would need the owner to take it on.

Six questions, then you get the actual size of the system your roof would take and how much of your power it would cover. Whether we ever speak after that is entirely your call.

No phone number needed until the last step, and only if you want one.

Question 1 / 6

Where is the roof?

Street address and ZIP is enough. We use it to pull the roof outline and the sun angles for your block.

Service address

Question 2 / 6

What does a bad summer month look like?

Your highest bill of the year, roughly. Guessing is fine — drag until it feels right.

$280

$80$700+

Question 3 / 6

How old is the roof?

Panels last twenty-five years. If the roof underneath has five left, that matters, and we would rather say so now.

Question 4 / 6

How much shade falls on it?

Think about mid-afternoon in July.

Question 5 / 6

Do you own the home?

A lease runs twenty-five years and attaches to the property, so this is the one answer we cannot work around.

Question 6 / 6

Where are you in this?

Answer honestly. "Just curious" gets you the same number as "ready" — it only changes whether anyone follows up.

Then this is not for you yet — and we will not waste your time pretending otherwise.

A solar lease attaches to the property for twenty-five years, so it has to be signed by whoever owns it. If your landlord is the sort who might be interested, we are glad to talk to them.

Estimated production a year

An engineering estimate from what you told us, not a quote. It assumes a standard 400-watt panel and average sun for your area, and it says nothing about price — the real number depends on your roof planes, your utility rate plan and a shade study. We would rather show you a size we can defend than a saving we cannot.

One thing worth knowing before you compare offers

The 30% federal tax credit for a system you buy expired on 31 December 2025. Pay cash or take a loan this year and the federal credit is zero. Third-party-owned systems still qualify under Section 48E — the owner claims it and passes the value through in your rate. Sunrun is the owner. General information, not tax advice.

So — what do you want to happen next?
