Grid-tied solar electricity (or photovoltaic, “PV”) allows you to generate your home’s electricity whenever the sun is out; you can either use the solar power as it’s created, or export it to the grid and earn credits. Further, when the rate of electricity goes up, your solar array increases in value proportionally.
- Lock in a fixed rate for electricity for 30+ years
- Reduce carbon pollution from coal, oil, gas, and nuclear power plants
- Less reliance on energy sources “from away” and the power grid
Save Money and the Environment
More than 60% of the electricity generated in New England comes from natural gas and oil, followed by nuclear (14%) and coal (9%). Maine and New Hampshire emit over 10,000,000 metric tons of C02 emissions annually, a result of burning over 50,000,000 gallons of oil and 2,800,000,000 lbs. of coal.
Solar photovoltaic panels, in contrast, generate clean solar electricity whenever the sun shines, year-round. Maine, New Hampshire, and Massachusetts boast 33% more sunshine than Germany, a world leader in solar energy. The technology for these panels is mature and reliable, resulting in systems that are expected to work for 40-50 years even in New England’s tough climate.
Solar electricity is local electricity, meaning that power is generated where it is used and does not have to travel great distances over transmission lines. This is a more efficient use of electricity that reduces strain on the electric grid. When your photovoltaic system generates more power than you are using, it helps to offset the cost to power your neighbors’ homes.

How Does Grid-Tied Solar Electricity Work for Your Home?
Grid-tied photovoltaic arrays require no batteries, no complex wiring, and no moving parts. Instead, they inter-tie directly with the grid (hence the name) allowing you to use the grid itself as a big battery. When your PV system produces more electricity than you need, that electricity is fed out to the grid and you receive a credit. When you consume more electricity than you produce (at night, on rainy days) you will draw that power off the electric grid as you do now. The utility reconciles credits with usage on a monthly basis and will you receive a bill for the difference (and can carry credits forward up to a year). This process is called net metering.
Retail net metering is currently protected and accessible for new customers in all the states where we offer service: Maine, New Hampshire, Massachusetts, and Vermont.
Grid-tied PV Animation
Bobby’s good buddy Francis gets some solar panels installed on his house, and explains how grid-tied solar electricity works and why it’s a great investment (ever wanted to bottle up the sunshine from summer and pop it open in winter? Yep, we got that!)
How a Grid-Tied Solar Electric System (With No Battery Backup) Works
Sunlight causes electrons to move through the wiring connecting your home’s solar photovoltaic panels, creating direct current (DC) electricity.
2) Solar inverter converts DC power into AC power
The DC electricity produced by the solar panels is inverted into alternating current (AC) electricity that can be used in your home. The AC electricity flows into your circuit panel and is available for any active electric loads: lights, television, computers, refrigerator, electric vehicles, etc.
3) Excess power is sent to the grid
If your solar photovoltaic production exceeds your demand, then the extra solar electricity is pushed from your home out to the grid. A separate meter tracks this exported electricity. At the end of the month, the utility reconciles the difference between your solar production vs. electrical consumption, and you either earn a credit or are billed accordingly.
What Happens when the Power Goes Out?
Because grid-tied systems are grid-dependent, they will shut down when the connection to the utility is lost (this is a safety regulation that prevents PV systems from accidentally backfeeding and injury utility line workers). However, if you wish to maintain electricity in the event of a power outage, the ability to integrate battery storage with a grid-tied PV array is possible.
Why Invest in Solar?
Solar energy is one of the safest investment options on the market today, delivering:
- 100% guaranteed financial return on investment (you get all of your money back, then an ‘annuity’ for decades in the form of avoided electricity costs)
- Environmental return on investment (eliminate thousands of pounds of CO2 emissions annually)
- Home equity return on investment (solar is proven to increase the value of any property by lowering cost of ownership)
- Community return on investment (everyone benefits from cleaner air & reduced dependence on fossil energy)
Solar Energy Economics
Quite simply, owning your own solar electric array is the way to get the best price 40 year price of energy, compared to any other source. Consider:

Solar photovoltaic system ownership comes with a powerful peace of mind: no matter what happens, you own a certain amount of your electric supply. As the cost of electricity increases, you pay no more for the same amount of electricity generated by solar. When the utility rate for power goes up, your solar power is worth proportionally more.

What Our Customers Say
I will say this about ReVision Energy: Of the various contractor and service personnel I’ve had they are by far the most professional I have ever encountered. From initial consultation to design, installation and even on my one (minor) service call, they were always polite and attentive. In an era when service personnel think nothing of arriving late, they always called on approach, cleaned up after themselves on a daily basis and often asked if I had any questions. In the design phase they were flexible enough to take my suggestion of adding more PV panels by reconfiguring their layout. Balancing this, they actually advised against a further addition of a whole new section of roof panels as being unnecessary and not cost effective. In that behavior they acted as a “trusted advisor” – the highest compliment I can give a contractor. I highly recommend them and have done so with one neighbor plus a friend, both of whom have contracted with ReVision as well.
