Solar incentive and tax credit changes in 2014
Builders interested in providing solar technologies for home buyers should be aware of 2014 changes in Energy Trust residential incentives and the Oregon Department of Energy Residential Energy Tax Credits for solar electric systems.

The following changes went into effect January 1, 2014:
  • Energy Trust now offers separate incentives for residential customer-owned and third-party-owned (leased) systems.
  • Energy Trust incentive caps increased for residential customer-owned systems in both Portland General Electric and Pacific Power territories. Additionally, the per watt incentive rate has increased for customer-owned systems in PGE territory.
  • The Oregon Department of Energy reduced the Residential Energy Tax Credit from $2.10 per watt to $1.90 per watt. The project cap of $6,000, or 50 percent of cost, remains the same.
 2014 Energy Trust residential solar electric incentives
  Incentive Rate Project Maximum Incentive Rate Project Maximum
PGE Residential Solar Electric Incentives:
Customer-owned $1.00/watt $10,000 $0.75/watt $5,000

Happy Holidays and Generators

If you leave your homestead during the Holidays, remember to set your auto gen start to auto! You want your batteries to be happy when you get back so the lights come on. We've had customers come back to flat batteries because the switch was in manual off, and other customers come back to an empty fuel tank because they were charging when they left, forgot to switch to auto and the generator ran itself out of fuel :(

This one is an 80 kW John Deere turbocharged diesel with plenty of fuel. Large or small, Willpower will get you the energy you want!

Happy Holidays

Solar Basics

Solar Efficiency is determined by the Total Solar Resource Factor (TSRF) at a given location. Solar Collectors gain their maximum efficiency and power output under full direct sunlight. Maximum efficiency and return on investment (ROI) of a stationary PV system is achieved when solar panels are oriented between Southeast and Southwest at a 15º to 45º tilt, and experience no shading from trees, buildings or other objects throughout the day. A roof with an east-west peak and a south face makes an ideal and cost-effective location for a solar array.

Pole, ground mount and pole mounted trackers are also popular solutions.

If you think you have a suitable site for solar power, Willpower Electric, LLC will be happy to make an accurate assessment for you. We will determine your anticipated annual solar power production from the available space, calculate the TSRF, and accurately predict the expected annual savings on your power bill.

Willpower Electric, LLC’s design process includes obtaining Electrical Permits, Energy Trust Incentive Reservation, and Oregon Department of Energy Residential or Business Energy Tax Credits when applicable. We also provide the necessary documentation to receive the 30% Federal Renewable Energy Tax Credit for businesses or individuals.

Installation and follow through include system commissioning, final inspections by local Building Department and Energy Trust, a complete and bound owner’s manual, training, and an unconditional 2 year warranty on materials and workmanship in addition to manufacturer’s warranties on inverters, solar panels and balance of system components.

Let us know your questions.

Winter Battery Blues

We received a call from an off-grid customer yesterday who is suffering from severe winter battery malnutrition! No matter what kind of system you have, a few simple steps will help you get through winter comfortably.

1. Check your water! Don't overfill, 1/4" below the filler neck is fine.
2. Review your monitor operation. It's amazing how many people forget to look at their emeter or trimetric, review the functions and understand them. Now's the time before the rains and fog come.
3. Double check your string input volts and current to make sure the system is still operating within normal specs.
4. Check out your generator and fuel supply.

Without a doubt, thrift is an admirable quality, but feeding your batteries well is your best investment! Your solar charge will not likely keep up with demand, but don't be tempted to only run your generator to put back enough kilowatt hours to get by. All batteries should be fully charged once a week and flooded batteries equalized once a month. Yes, you'll need to run your generator, but if you follow your battery manufacturer's instructions for bulk charge voltage and absorb time, and don't let your SOC fall below 50%, you'll acheive long, happy lifetimes on that expensive battery bank.
(Efficiency tip: If you have a washing machine, do your laundry during the end of bulk charge and absorption cycle when the charge current is low and you have extra kw headroom on your gennie.)

If you need help doing a thorough maintenance and checkout of your system, feel free to give us a call. Have tools, meters and water, will travel!

Technology in charge controllers, inverter/chargers and auto gen starts has made leaps in the past 10 years. If you're considering upgrades, let us help you make choices that are right for your system and budget.

Winter Specials

Solar Module manufacturing is booming and our suppliers have responded with some great specials.
We're still committed to using American Made products, and use products made in Oregon whenever possible. This is our way of reducing the carbon footprint of doing business. When our products come from the West Coast, we're not paying the price of fuel or carbon emissions from the east coast or China.
Right now we have terrific pricing and can get a Solar System on your roof that will pay for itself in less than 10 years. Pretty good considering that solar modules are now coming with 20 year performance ratings, are expected to last for 40 - 50 years, and are then 99% recyclable!
If your roof gets lots of sun, give us a call today and schedule your free site survey ($400 value).BF
