Bay Area Solar and Battery Installation, With Zero Sales Commission

Yes, for many homes, but the math is different from before. NEM 3.0, officially the Net Billing Tariff, pays much less for solar power exported to the grid than the old net metering program did. That makes using your own solar power at home, and storing the rest in a battery, the key to good savings. Whether solar pays off for you depends on your usage, your utility rate plan and how much you can self-consume. Nabu Energy models this for your home, with and without a battery, so you can compare real numbers.

Your price depends on system size, roof type and condition, equipment choice and any electrical work such as a main panel upgrade. Adding a battery raises the total. We provide an itemized proposal so you can see exactly what you are paying for.

The final price depends on whether it is added to existing solar or installed with a new system, how many batteries you want, and whether your electrical panel needs upgrades. Powerwall 3 stores 13.5 kWh and is rated for 11.5 kW of continuous output.

Because under NEM 3.0, a battery lets you keep midday solar power and use it in the evening, instead of exporting it at low rates and buying power back at higher ones. It also keeps selected circuits running during a grid outage. How much it saves depends on your utility plan and evening usage. We size the battery to your actual usage, not a default package.

Start by checking that the installer holds an active California contractor’s license, and look up the number on the CSLB website. Then compare who does the work (the installer’s own crew or subcontractors), what the proposal includes, the warranties, and reviews and local references. Nabu Energy’s license is CSLB #1052356, and our in-house team handles design, permitting, installation and utility interconnection.

The federal residential solar credit changed under 2025 federal legislation, and rules differ for purchased systems and third-party-owned systems such as PPAs. State, local and utility programs also change.

Your solar system still powers your home during the day and sends extra power to the grid, but it shuts off during a grid outage. A standard grid-tied system without a battery or backup equipment does not provide power when the grid is down, for safety reasons. Without a battery you also export more power at the lower NEM 3.0 rates. You can add a battery later, but it is usually simpler and cheaper to plan for it in the original design.

A prepaid solar PPA means you pay up front for the electricity the system will produce over the contract term, instead of paying a monthly rate per kilowatt-hour as in a standard PPA. Because ownership and tax treatment differ from buying a system, review the full agreement and talk to a tax professional.

No. A prepaid PPA requires a payment up front, so it is not a zero-down option. The difference from a standard PPA is that you pay once instead of monthly. Review the proposal for the amount due, what it covers and the contract terms.

It means Nabu Energy does not pay sales commissions on the contract, so that cost is not built into your price. It does not by itself guarantee a lower price than other providers, since total cost depends on equipment, installation scope and contract terms. Compare itemized proposals side by side.

Nabu Energy does not pay commissions to salespeople on the systems we sell. Your proposal is based on the cost of the system and installation, not a sales incentive.

We handle the permitting and interconnection paperwork for you.

We choose equipment based on your roof, usage and goals, and explain the options in your proposal.

We are your first call if something needs attention.

Yes. Our in-house team prepares the design, submits permits to your city, schedules inspections and files the utility interconnection paperwork. You do not need to deal with the city or utility yourself. You can turn the system on only after the utility gives permission to operate, and we track that process for you.
