Welcome
Specialists in ultra high performance bifacial ground mounted arrays.
Optimize energy usage and cut costs with New Hampshire Solar's unique bifacial arrays and residential battery backup systems.
The simple test that started our love for bifacial solar modules years ago
- This is the simple frame that was set up for our initial March 2017 testing of a 295 watt Prism bifacial solar module. The 295 watt rating is what is known as the STC, which is the power rating based on the harvest from the front face of the module only
Proof of the extra power! - the solar harvest from the very first bifacial solar array that we built
Different types of Ground Mounted Solar Arrays
This is the underside of the array shown on the welcome page and is typical of a fixed ground mount set at the usual 35' pitch. Note how the sunlight filters through between the individual solar cells that make up a module and creates the very cool shading pattern on the white stones below.
Fixed ground mounts are the least expensive bifacial ground mounting but will sti
This is a 15 module MT Solar Tlting Top of Pole mount and though a little more costly than a fixed ground mount it is brilliant all around solution. The tilt of the array can be quickly changed with the included awning hand crank. By changing the angle of the array seasonally to directly face the noontime sun about 5-7% of additional power front side power can be captured from the sun. With an
The underside of a MT titlting single pole mounting, the awning crank can be seen just to the rear of the 8" main pole. Most of our clients only change their pitch four times a year, setting it to 35 degrees for the Spring and Fall months, 25 degrees during the summer, and 50 degrees during mid winter. The additional advantages of the pitch changes are that it is very easy to mow under the fl
The BIG Dog - an All-Earth dual axis tracker. These arrays are somewhat large and costly but they do produce far more usable power than any other type of array. A tracker automatically adjusts both it's pitch and azimuth continuously so the front of the array is always facing directly at the sun. The midday production isn't all that much greater than a well placed fixed or tilting ground mount,
Homegrid 24 kWh LithoFerroPhosphate battery
Home energy storage has revolutionized the solar industry.
The Homegrid battery shown in the photo is most typivcally used in our off-grid installations and the beauty of it is both that the chemistry of an LFP battery is totally safe, and that the capacity of the battery can easily be expanded. For grid tied installations we generally recommend SolarEdge's Li-ion Energybank system. Both systems will give you total control over how you energy is stored and fed back into your house. We generally recommend to our client's that the bulk of the excess midday solar production stored in your battery be held in reserve in case of a grid outage during the winter months, but be self consumed in your home during the summer months. By directly self consuming the stored energy during the evening the 25% net metering discount is avoided, thus saving you even more money.
The primary reason that most of out client's add a backup system however isn't for the financial savings, it is to have a source of power during grid outages. Within seconds of a utility grid outage the system will automatically switch over to your battery and solar array and your home will be fully powered. You might run out of power overnight if you fully deplete the battery, but once the sun again rises your system will again re-awaken to power your home and recharge the battery. You will never be fully out of power, even if the grid is out for weeks or even months!
But what if its December, the weather is lousy, and you aren't getting any solar harvest? Simple, just hook a small generator into the backup system and run it just long enough to fully recharge your battery. This might take a few hours, but at least you won't need to listen to it 24/7!
What's the main reason to add backup to your solar system?
Simple, to have power during grid outages, especially long ones. Without a battery backup system a solar array must shut down during an outage to avoid sending power back into the lines while they are being repaired. A system equipped with backup however will automatically "island" itself away from the grid and remain alive.
