Xcel Energy offers what is called rec credits
This is a fee Xcel Energy will pay the homeowner for every kWh produced by the
system
As of Dec 4, 2012 Xcel Energy is no longer taking applications for small programs
(anything under 10 kW)
Medium programs are still open thru year end 2012
The small program will open in January of 2013 and the pricing structure will be
released at that time.
As the information is released we will provide it to you
Grand Valley Power
• Grand Valley Power does not have limitations
on system size like Xcel. They will buy back
your excess power at a wholesale rate which is
at 4.5 cents per kWh. This utility does an
audit at year end and pays one time. This
Utility down not offer rebates.

Basic Solar
Basic Solar Information
kW PV system generates approximately 150 kWh per month
A 1 kW PV system is approximately 6 solar panels
A 1 kW PV system takes approximately 100 sq. ft. of flat space
A 3 kW PV system takes approximately 25 hours to install
A 3 to 4 kW PV system is enough to power the average US home
Solar Water Pumping is an easy way to save money in rural areas
The Power Grid acts like a high-performance battery by providing needed power when
required
Solar Panels have a 25 year warranty
Inverters have a 10 year warranty
Solar Panels are much more efficient compared to 4.5% efficiency in 1954
A tracking device on pole-mounted PV Solar systems can increase efficiency by 20 to 40%
Local Governments can't stop you from installing a Solar PV Solar system on your home or
business
Net Metering allows a PV Solar system to spin our electric meters backwards during high
production hours
Why add Solar to your business
•
1. Solar is here to stay. It is one of the few renewable resources that is virtually universally
accessible. Wind and water power depend upon local conditions, but the sun is everywhere.
•
2. The energy industry generally is the place to be. Politicians, businesses and non-profit
organizations will continue to invest in alternative energy far into the future.
•
3. You can feel good about what you are doing. Building a solar business is a great way to give
something back to the world and provide clean power for future generations.
•
4. Solar is how we will move forward as a world. With resources dwindling around the planet
and no magic bullet, it will be a matter of using various energy strategies to satiate our
energy needs.
•
5. Solar power specifically requires very little technical knowledge and no specialized
background. Anyone can get into the field and succeed if they work hard at what they do.
•
6. Getting into the solar power business will expand your horizons. You will learn a new trade
and a new set of skills and can grow your resume for the future while doing something new.
•
7. Even in a recession industry, the energy industry is a great place to be. This is particularly
true at the moment because one of the ways out for the global markets is developing new
energy technologies.
FAQ’S
•
•
What conditions are necessary?
The solar array must have a reasonable amount of non-shaded, unobstructed
space, either for a roof, ground or pole mounted system, during the key sun hours
of the day. A southern exposure is ideal, but east and west facing roofs can capture
over 80% of the power of a south- facing roof.
Will a solar system produce enough energy to handle all my electric needs?
You will have to determine how much energy you use and how much of an
investment you want to make. Look at your electric bill and determine how many
kilowatt hours you use over a year’s time and on average for a month. Most
homeowners and businesses install a system on the roof with adequate sun
exposure that produces between 10%-40% of their needs. In some circumstances,
a system may be installed also on the ground or on a pole mount. Any installation
of solar should be preceded by energy efficient upgrades to the building or if new
construction, built to promote energy savings. Energy not used is energy you
need not buy, either in electricity from the grid or from a solar panel.
FAQ”S
•
How much electricity will my solar energy system produce?
The amount generated will depend on the size of the system you install,
orientation of the system and shading. Typically a solar energy system using 100
square feet of solar panels will generate 1,000 -1,440 kWh per year.
•
How will I know if the system is working?
Your inverter display will show you how much power is produced at any given
time. Solar energy systems with miro-inverters, an increasingly popular
alternative, allow you to see how your system is performing on a module to
module basis.
What happens during an electric outage if my system is tied to the grid?
Grid connected solar energy systems will immediately shut down to protect your
electric provider’s linemen.
•
•
How durable is a solar energy system?
Systems must pass a standard set of tests and are built to withstand winds up to
125 mph and 1-inch sized hail. To meet these standards, the racking system and
solar panels must be installed to the manufacturer’s specifications. Racking
systems but be bolted to rafters, not decking.

FAQ’S
May I add battery backup at a later date?
Yes, though if you start with some battery backup, it is easier to add more than starting
with none. If you start without a backup battery, it will be rather expensive to add
batteries, due to the high cost of adding a different type of inverter.
If I live in a neighborhood with a homeowner’s association, will I need their approval?
The Basics
The law went into effect on August 6, 2008
HOA’s are not allowed to prohibit the installation or use of renewable energy devices or
energy efficiency measures within their communities based upon aesthetic rules and
restrictions.
Residential and commercial property owners have the legal right to erect and use
renewable energy generation devices on property they own. These include:
– Photovoltaic (PV) solar electric panels
– Solar thermal systems (solar water heaters)
– Solar lighting systems
– Wind electric generators
Residential property owners also have the right to install and use energy efficiency
measures on property they own. These include:
– Awnings, shutters, trellis, ramadas, or other energy reducing shade structures
– Garage or attic fans
– Evaporative coolers
– Energy-efficient outdoor lighting
– Retractable clotheslines
FAQ’S
• Any and all of these devices and measures must meet all building code,
electrical and bona fide safety requirements.
• Residential property owners do not have the right to erect or install
renewable energy devices or energy efficiency measures on limited or
general common elements of the Common Interest Community(CIC). This
is particularly important for condominium and town home communities,
where residents may not own the exterior of their units.
• Unreasonable restrictions on renewable energy devices are void and
unenforceable. This law overrides any covenants, restrictions, or
conditions contained in any deed contract, security instrument or other
instrument affecting the transfer or sale of, or any interest in, real
property (residential or commercial) that attempts to restrict or prohibit
the installation of solar energy devices and wind-electric generators.
• HOA’s can impose reasonable restrictions on the dimensions, placement
and external appearance of the renewable energy device. However, an
HOA/CIC cannot:
– Prohibit the installation or use of a renewable energy device.
– Significantly increase the cost of installation or use of the renewable energy
device.
– Significantly decrease its performance or efficiency

How long will installation take?
It will typically take five to ten days for a professional installation for a home. For
commercial installations, consult your solar installer.
OPERATION PERFORMANCE and QUALITY
What happens at night?
Nothing unless you have a battery backup. The solar panels must be exposed to
sunlight to produce energy, but batteries can store that energy.
What happens on cloudy days?
The bulk of your electricity production will take place under sunny conditions.
Output is directly proportional to the amount of sunlight available at any given
moment. A system can generate 50 - 70% of its typical output under bright
overcast conditions, but production will continue to diminish as less light reaches
the system.
Is temperature important?
Solar energy systems typically operate in temperatures ranging from -13 to 122
degrees Fahrenheit. Though output drops as the system gets hotter in the summer,
the increased daylight hours ultimately increases energy production.
FAQ’S
•
•
•
Is the solar energy system warranted?
Solar energy system modules typically carry 20-30 year warranties. The racking system
and inverters should also carry warranties. Be advised that for warranties to apply,
these components must be installed to manufacturers’ specifications. Make sure that
your installer provides a warranty on installation services.
If this is a grid tied system, does the electricity produced by the system go directly to
my house or to the electric provider?
All the energy produced by your solar system flows to your house if all the energy being
produced is needed. But sometimes only some of the energy is needed (you are at
work, the AC, washer, dryer , ect.) and the excess electricity from the solar array will
flow to the electric provider. This is a simplified version of the fluctuating path of the
energy produced.
What is net metering?
If your solar energy system is grid tied to your electric provider and it produces more
power at any given moment than the property consumes, the extra power will flow to
the electric provider. Over any month when a solar energy system sends more power
into the electric grid than the homes takes from the grid, the difference or net, will
result in a credit determined by the electric provider .Net metering “credits” can be as
little as the base rate the utility pays for wholesale power or as generous as the retail
rate you pay as a customer.
FAQ’S
•
What are the incentives available for homeowners installing a solar energy
system?
The most up to date information on federal, state and local incentives is found
athttp://www.dsireusa.org/
Federal: Homeowners are eligible for a 30% tax credit on the final cost of a solar
energy system, after any state or local incentives.
State: There are currently no state incentives for homeowners who have installed
a solar energy system
Local: Homewoners should check with their electric provider to see if incentives
are available.
Incentives for businesses? Businesses also have federal tax credits and may have
incentives available from their electric provider. The state allows a corporation or
other entity subject the state franchise tax to deduct the cost of a solar energy
device from the franchise tax. Entities are permitted to deduct 10% of the
amortized cost of the system from their apportioned margin. Again, we
recommend http://www.dsireusa.org
FAQ’S
•
•
•
What size system should I get?
The Utility will delegate how large your system should be. Your system size in most utilities is
120% of your usage averaged out over the last 12 months. Remember you may not cover all
your energy needs with a solar energy system. The only other condition in deciding proper
system size is the amount of suitable space available on your roof. To be suitable, you must
have unobstructed, non-shaded roof area, either flat or a sloped, at an orientation other than
North. You need roughly 120 square feet of roof space for each kW that you wish to produce.
How much does a solar pv system cost?
The total cost for purchasing and installing a solar energy system is based on the size of
system you require and the specific details of the layout of your property. The price of solar
modules has dropped dramatically in the last few years. As of September 1, 2011, installed
systems are ranging anywhere from $4-$7 per watt before any available incentives or tax
credits.
Will a solar energy system increase the taxes on my home?
You will not be taxed on your solar energy system if the energy produced is used for your
property.. The form to declare a renewable energy property tax exemption must be filled
out yearly. http://www.window.state.tx.us/taxinfo/taxforms/02-form06.html
•
May I increase the size of my system at a later date?
Absolutely, provided you have the unshaded space
