Solar on Long Island
http://www.LongIslandBuilders.com
• Monthly Bill of $240 x 12 = $2,880/Year
• $2,880 x 10 years = $28,800
• $2,880 x 20 years = $57,600
• $2,880 x 30 years = $86,400
*And that’s with no rate increases!
With a 2% annual electric rate increase, it is over $100,000!
Our region pays the 2nd highest electric utility rates in
the entire country!

Why is Long Island Going Solar?

1.Lease – you pay a fixed, monthly bill for the
“rental” of the equipment. Usually a 20-Year
Term. Payments USUALLY go up EVERY year.
2.PPA – Power Purchase Agreement – You pay
for every kilowatt hour of energy you use.
Usually a 20-Year Term. Payments ALWAYS go
up EVERY year.
3.Buy – Financed or purchased outright. The
power produced by your system is yours. No
monthly payments unless financed and those
go away at end of term of your choice.

How Much Solar Does a Property Need? Every system is different. Depends on:
Average homes in our area…
Spend around: $200/month
Use around: 12,000 kWh/ year
Average Homes Needs:
10 kW system
800-1,000 sq ft of roof space
Annual energy consumption
How much solar fits on roof
Pitch, orientation, and shading

RESIDENTIAL & COMMERCIAL SOLAR REVIEW
http://www.LongIslandBuilders.com
Solar System: Most systems today are Grid tied, meaning no battery back up involved.
The typical system includes the panels on the roof, which generate Direct Current from the
sun’s rays. This D/C current is carried by a conduit to an inverter, which converts the D/C
power to A/C for use in homes and business. From the inverter, the electricity flows into the
service panel, with excess power flowing back to the Grid.

Net metering is a program offered by a utility company for customers that
install renewable energy systems to generate their own electricity that can
be used to offset a portion of the electric energy provided by the utility. Any
excess energy generated by the customer during the monthly billing cycle
would be sold to the utility company and credited to the customer.

Some Obvious Questions about Solar
Do solar panels need to be cleaned?
Except in unusual circumstances where panels are in close proximity to a dusty or
heavily polluted area, solar panels do not require cleaning. In New England there is
enough rain to give solar panels all the washing they need.
Does a roof need to face south?
The ideal roof slopes towards the south, since southern exposure will maximize the
efficiency of solar panels. But even if your roof is east or west facing, you can still get
strong results. If there is a flat roof we can orient the panels to maximize efficiency.
How much roof space is required for a solar electric system?
For every kilowatt (kW) installed, a solar system takes up about 100 square feet, so an
average solar system takes between 500 and 600 square feet.
What size solar system is needed?
The size of a solar PV system depends on how much electricity is used. When we
design an array, we start by looking at utility bills to determine the usage. From there we
assess the specifics of a client’s site, including building orientation and roof shading to
see how much energy it could generate. We then offer the client a detailed proposal –
usually with two or three optimal system sizes - specific to their situation.
