FAQ

The questions we get asked most.

How it works

5 questions

Do I need a battery to have power at night?

No. At night you use the net metering credits you banked during the day.

What happens in a power outage?

Without a battery, the system safely shuts off during an outage. With one, it keeps the house running.

Do net metering credits expire? Can I give them to someone else?

They don’t expire; they roll forward. You can allocate them to another meter in the same utility territory with a Schedule Z form, but not to a property in another state.

How long does the whole process take?

About 30 to 45 days on average, from signed documents to a system that’s on. If the utility routes your interconnection to its Complex Process, add about 45 days.

Do I need a second electrical panel, or a service upgrade?

Not a second panel. A service upgrade is sometimes needed: a 200A upgrade runs about $5,000, and we do them often ahead of solar.

Equipment and warranties

4 questions

What inverter do you use?

We work with several inverter manufacturers, microinverters included, and recommend the one that fits your roof, your usage and your goals.

What’s the warranty picture?

Our workmanship warranty is 10 years and covers roof penetrations, the electrical work and the install itself, labor included. It is paired with a 25-year equipment warranty.

What if you’re acquired, or go out of business?

Manufacturer warranties sit with the manufacturer and aren’t affected. If we were acquired, our workmanship warranty would usually be taken on by the buyer. If we stopped trading, it would end. We’d rather tell you that straight.

How are the panels attached, so the roof doesn’t leak?

IronRidge Aire racking with Halo UltraGrip attachments: neoprene foam, an adhesive seal and gasketed screws, engineered to hurricane-zone standards. Roof penetrations are covered by our 10-year workmanship warranty.

Cost and financing

5 questions

Do I pay my monthly bill to the utility or to you?

Your home uses your own production first. Surplus is exported and banked as net metering credits, and you only pay the utility when you use more than those credits cover. If you financed, you pay the lender.

Do I need money up front?

No. Both the solar loan and the lease need nothing out of pocket, and we don’t ask for any payment until we’re ready to install.

Can my loan payment go down later?

Yes. The loan reamortizes at months 12, 24 and 36. Put money toward it in one of those windows and the fixed monthly payment adjusts down. There are no prepayment penalties.

How do I know what I’ll actually save?

We start from your real usage history and size the system to produce about 100 to 105% of what you use in a year. If we only have a month or two of your usage, we’ll tell you the projection isn’t reliable rather than present it as fact.

What happens if I sell the house?

With a solar loan, the balance is paid off before the deed transfers, and most owners settle it from the sale. With a lease, the arrangement is with the leasing company.

Batteries

4 questions

Should I get a battery?

Often not. Where the grid is strong and outages are short, net metering already covers you. A battery earns its place where outages are frequent or last for days.

Does a battery switch over automatically when the grid goes down?

Yes. A backup battery detects the outage and switches your home over to battery power automatically.

Can I add a battery to solar you didn’t install?

Yes. A battery can be retrofitted onto an existing solar system, or run standalone with no solar at all.

What does a battery cost?

Depending on the product chosen, all-in battery installation costs range $10,000 - $13,500.

Roofing

3 questions

My roof is old. Should I replace it first?

If it’s near the end of its life, yes. The roof can be rolled into the solar loan, and almost everybody who needs one does exactly that.

What does it cost to take the panels off later?

About $250 to $300 per panel to remove and reinstall, so it scales with the size of the array. That is the number that makes doing the roof first worth it.

Can I replace just the part of the roof under the panels?

Yes, but watch the valleys. Where two roof surfaces meet, an adjoining surface may need doing too, to keep the shingles watertight.

Service

4 questions

How would I know something’s wrong?

The inverter’s phone app shows real-time production, plus error codes and connectivity warnings. That includes daily, monthly and lifetime production.

What maintenance does the system need? Do the panels need cleaning?

Very little. The panels have a self-cleaning surface and rain handles seasonal pollen and dust. If yours ever do need a clean, we can take care of it.

Is fixing things included?

Yes, for 10 years, under our workmanship warranty.

Will you service a system you didn’t install?

Yes, including systems whose original installer has gone out of business.

Commercial

3 questions

Who owns the system and the tax incentives?

With a loan, you or your LLC own the system outright and keep the incentives. With a lease, a third party owns it and takes them.

What if I sell the building?

If it is financed with a solar loan, the balance is paid off before the deed transfers. Most owners settle it from the sale proceeds.

What do you need from me to quote?

Twelve months of utility bills, roof or site plans or access for a site visit, and whether you own or lease the building.

Electrical

7 questions

Can a panel upgrade go into my solar quote?

Yes. A typical 200A upgrade is about $5,000, and adding solar at the same time saves you $1,000 on the upgrade.

What do you check before a battery or an EV charger?

Panel capacity and available breaker space come first. They decide whether an upgrade is needed.

My utility says it’s changing my meter or transformer. Does that matter?

It can. Where the utility is planning its own work on your service, it’s worth knowing what they intend before an application goes in, so you aren’t asked to fund transformer costs.

Can my insurer or lender make me rewire?

It happens. Some insurers won’t write or renew a policy on a home with knob-and-tube or aluminum wiring, and some lenders require it be addressed before they will finance.

Can you give me a price over the phone?

Not a fixed one. Every house is different, so the price and the timeline come after an inspection.

What should be decided before the walls close?

The service size, and where a future battery would live. Battery siting rules vary by town and inspector, so confirm them before framing is closed up.

Can you work around our close-up dates?

We coordinate directly with your carpenters and GC on conduit routing and wall close-up dates, as we have on multi-unit jobs. We confirm our current schedule before we commit to dates.
