Is solar worth it with PG&E? Panels alone vs. solar + battery

This guide concerns a new installation. An existing customer with older net-metering terms faces a different decision; do not assume a neighbor’s historic savings will apply to your new system.

PG&E’s Solar Billing Plan separates grid purchases from export credits. Their values depend on when energy moves. Check both your delivery service and generation provider, including any community choice aggregator, before accepting a savings projection.

A home that uses electricity while its panels are producing has a different pattern from a home whose biggest loads run after sunset. An annual production total alone cannot show how much grid electricity either household will still buy.

Ask the installer to use interval usage where available. A monthly bill can help verify your account and annual consumption, but it cannot by itself establish an accurate hour-by-hour battery dispatch model. Include an EV or heat pump only if you have a realistic plan for adding it.

Storage can move some solar production to a later time. The financial question is how much additional utility spending that avoids after accounting for foregone export credits, charging losses and the installed battery cost.

A battery that improves the combined package’s electricity savings may still have a weak incremental return. Request a separate price and a separate annual-savings estimate for adding it. Keep the value you place on outage protection separate from the dollars you expect to save.

PG&E describes continuing charges and credits under the Solar Billing Plan. The proposal should show remaining purchases, export compensation and applicable fixed charges. Ask how annual reconciliation is handled rather than assuming every month will look the same.

Use the current tariff for your account instead of a single statewide average. A model with aggressive future utility-price increases can make payback look better without improving the system installed on your roof. Ask for a flat-rate sensitivity case too.

Wait for better information if the roof needs work, the design has unresolved shade, or the seller will only show a bundled solar-and-battery price. A large system that exports substantial energy is not necessarily better than a smaller system suited to the household.

Do not assume a federal homeowner credit will pay for part of a new 2026 installation. Confirm any battery incentive with its actual program and eligibility rules. Treat unconfirmed rebates as zero in your starting comparison.

Our quiz provides a starting solar estimate using your bill and site answers. It is not a battery dispatch model, a roof survey or a binding installation price. Use it to decide whether a more detailed review is worth pursuing.

If you request an introduction, ask the installer to provide a written recommendation with and without storage. That is a concrete question they can answer using your usage, tariff and installation constraints.

Examples on this page illustrate the comparison method; they are not installation quotes, financing offers or guaranteed savings. Use your current tariff and written proposal for a personal decision.
