Many homeowners have questions about what happens with their electric bill after installing solar. Since 2008, My Generation Energy has helped homeowners across Cape Cod and the South Shore go solar with start‑to‑finish support.
This guide explains what happens after you install solar, how your bill will change, how seasonality affects your usage and credits, and how working with an experienced solar company can help you long after your install.
What Happens After You Install Solar?
Once your solar installation is finished, there are a few important steps before your system is fully active and online. Solar production and net metering credits won’t appear on your monthly bill until the following steps are completed.
- Municipal inspection and meter change: After installation, My Generation Energy coordinates an inspection from your local town, which is required before connecting to the grid. Your utility then schedules a time to swap out your meter, typically within about two weeks.
- Permission to Operate (PTO): After the meter change, your utility issues a Permission to Operate letter, allowing you to turn on your solar PV system and start sending power to the grid. My Generation Energy returns to your home and assists with that final turn‑on.
- Net metering enrollment: Utilities like Eversource and National Grid offer net metering programs that track both the electricity you use from the grid and the excess solar you send back, turning that extra production into bill credits you can use later. My Generation Energy handles the net metering enrollment with your utility as part of your installation.
- REC tracking (if applicable): For qualifying systems, your solar production can also earn Renewable Energy Certificates (RECs), which are separate from your bill credits and can be sold to add extra value to your solar savings. My Generation Energy provides incentive guidance and connects you with REC partners so your system can start generating and selling RECs.
What Will My Electric Bill Look Like After I Go Solar?
All of the residential solar systems we install are grid‑tied, so your utility will continue to send you an electric bill every month. The difference is that your bill now shows both how much grid electricity you used and how much electricity your solar panels sent back to the grid.
In many cases, homeowners see very low, zero, or even negative bills as net metering credits build up. Those credits do not expire in Massachusetts, so you can use them later when your solar production drops and your electricity use increases.
Key things you’ll see on your bill include:
- Your usage from the grid, which may be much lower than before solar.
- Your net metering credits, often labeled “Net Meter Credit” or “NET MTR CRDT,” which appear as a negative line item under delivery charges when your solar production exceeds your usage.
- A running credit balance, which carries forward month to month and can offset future charges when your solar panels produce less or your usage is higher.
Will My Electric Bill Change Depending on the Season?
Solar production and electricity usage in New England vary throughout the year, and your bill will reflect those changes. Looking at a full year of production, most Massachusetts solar PV systems show higher output in late spring and summer and lower output in late fall and winter, but net metering helps balance these seasonal highs and lows on your bill.
- Spring and summer: Longer days and stronger sun mean your panels produce more electricity, often more than your home uses. This is typically when you build up net metering credits and may see zero or negative bills.
- Fall and winter: Shorter days and increased usage mean your panels produce less relative to your needs. You may use your accumulated net metering credits to offset higher bills in these seasons, smoothing out costs over the year.
