SO, HOW DOES IT WORK AND HOW DO I SAVE MONEY?
SOLAR PV ELECTRIC:
Solar PV electric power generation systems produce clean, free energy using the ultimate renewable energy resource, our own Sun.
A home with unshaded roof space during at least the middle 6 hours of the day will produce satisfactory amounts of power. A southern exposure is ideal, though eastern and western orientations can work as well.
In a typical residential installation solar panels are mounted on the roof, using an aluminum racking system and flashing with stainless steel bolts. Photovoltaic (PV) cells beneath the tempered glass surface, convert the sun’s light into DC electricity.
That power is produced without emitting any harmful green house gasses or other pollutants. Putting a 10kW system on your roof can have the same beneficial environmental effects as planting 5 acres of trees or not driving your car for one million miles.
The panels are typically connected to each other in series, in one or more strings. Similar to the way that batteries in a flashlight are connected. The DC power is brought down off the roof in conduit to one or more inverters mounted on exterior or interior walls. Inverters convert DC electricity into AC power the home can use. The power is routed to the home’s main electrical service panel. Whenever the solar PV system is generating power, the home will use that power first instead of drawing from the utiliity.
The utility installs a net meter, that can track current flowing in both directions accurately. When the solar system is producing more power then the home needs, it flows backwards through the meter into the electrical grid creating an automatic credit on the account. When the system is not producing enough power for the home or it is completely off at night, power is drawn from the utility as needed.
At the end of the monthly billing cycle, if the system produced the amount of power that the home needed, the meter will appear to have not moved. If there was any excess power, it is carried forward as a credit in your ‘energy bank’ to be used the following month. At the end of the year any excess power is purchased by the utility.
Solar electric power systems are much more efficient in cold weather. However they produce more power in the summer, due to the significantly longer days.
On Long Island, residential solar installations are not subject to state or local sales tax and are exempt from increasing the property taxes for 15 years.
A LISEIA Member Contractor professional will come to your home and discuss how you can start using the power of the sun today. Save money, protect the environment, increase the value of your home.
Then sit back and watch your meter spin backwards.
Use the sun, it’s lots of fun!
SOLAR THERMAL HOT WATER (STHW):
Solar thermal hot water systems do not generate electricity. They instead create hot water that your home can use, supplementing the existing domestic hot water heating (oil, gas, electric, propane) by preheating the water.
This can be done in a variety of ways via a drain back or pressurized glycol system. STHW often allows you to more readily replace an aging DHW system with a modern tankless system as your primary solution, using a STHW system and tank to preheat the water which reduces the amount of work the primary system does.
Savings on oil, gas or electric are substantial. STHW systems for residential use take up very little space relative to PV electric, are very affordable and are good for the environment.
They can also be used in some cases to preheat the water for your home’s space heating system in conjunction with your boiler, to reduce your annual home heating costs for oil as well.
SOLAR POOL HEATING:
Solar pool heating is a variation on STHW, where the sun is used to heat pool water.
GEOTHERMAL:
Geothermal systems use the earth itself to heat or cool your home and in some cases preheat your domestic hot water as well. They are highly efficient systems that may eliminate your heating bill for oil or gas completely.
If you have electric space heating and air conditioning they will dramatically reduce your electric heating and cooling bills. Geothermal works best with forced air or radiant floor space heating systems and are best suited for new construction or remodeling.
A geothermal system used in conjunction with a solar PV system, can even create a Net Zero Energy Home where your oil, gas and electric bill net to zero every year, if you have sufficient solar resources to power the geothermal unit and auxilliarly electric heat.
