FAQ

  • How much money will I save on my electric bill?

It will depend entirely on the size of the system and your "site efficiency." Site efficiency is a percentage that represents the amount of total annual sunlight your system can capture. It is determined by looking at how much shade affects your system, what angle the panels are mounted at, and what direction they are facing. It is impossible to know your site efficiency without visiting your site in person. To provide some kind of baseline, however, we can say a typical 5kW system (5,000 watts) will produce approximately 550 kilowatt hours per month. The average home in Gainesville uses about 1,000 kilowatt hours each month, so a 5kW system would reduce your monthly electricity bill by 55%.  Our customers typically want their solar system sized to cover 90-100% of their electricity bill.

  • Will Solar increase my property value?

According to the Appraisal Institute's “The Appraisal Journal” of October 1998, the substitution of renewable energy systems for purchased utility services will raise the value of your property by a multiple of twenty times a dollar of avoided utility cost per year. In short, if your PV system makes $1,000 of electricity per year, your homes value increases by $20,000. To read the report go to http://www.ongrid.net/AppraisalJournalPVValue10.98.pdf

This means that your home would increase in value immediately by about the total net cost of the system. If you plan to sell your home, the buyer of your home will be able to afford a higher monthly mortgage payment because of the energy savings produced by solar system. In addition, realtors agree that in this challenging real estate environment, any feature that gives your home a competitive advantage over other homes will help your home sell faster.

  • Will my homeowners association allow me to put solar on my roof?

Florida State Statute 163.04 clearly states that homeowner associations are expressly prohibited from disallowing a solar electric system to be installed. (Please ask us for a copy of the statute.)

  • Will the surrounding trees be a problem?

This is hard for us to determine without seeing your property in person. Typically, unless there are tall trees in the SE to SW window of your sites location, tree shading should not be significant enough to prevent you from exploring solar options. A rule of thumb is to have no shading at least from 10AM to 3PM. Since the sun is higher in the horizon during the summer, tree shading usually provides more obstacles during the winter than in the summer. Solar Impact can provide a complete site analysis to determine the exact shading and impact that any trees will have on your system.

  • What is the best orientation For Solar?

The best orientation is SE to SW with South being the best. SE to SW orientations will result in only a slight annual energy reduction of 2% to 4%. We can even installs systems due West or East, but you can expect anywhere from 12% to 18% less production than a Southern orientation. If you have no shading issues, then adding a couple more solar modules to your system will compensate for these losses.

The optimum roof pitch or tilt angle is between 15° - 45°, with only 2% to 4% loss compared to the "perfect" pitch. Even a flat pitch will only result in about a 10% annual output reduction; however, we recommend to never have a flat array due to major soiling issues that will require unacceptable maintenance schedules and reduction of the system life.

  • Does it matter what type of roof I have?

Yes and no. All roof types can be installed with solar, but there is a sliding scale of difficulty (and cost). Metal and shingle roofs are the easiest to install, while flat and clay tile roofs are more challenging. It is worth noting that we do not have to penetrate a Standing Seam Metal Roof, because our racking attaches directly to the metal seams of the roof.

Different roofing materials require different methodologies which can impact the installation costs. We recommend never allowing amateurs or inexperienced contractors to penetrate a torchdown (membrane) or flat roof. Only experienced professionals should ever work with these difficult roofs.

If your roof will need to be replaced in the next ten years then we recommend that you replace it before having your system installed. We are happy to provide recommendations for roofing contractors we have worked with and trust.

  • What size solar electric system do I need?

The recommended size of your system depends on your power consumption. If you want to completely offset your current electrical usage from the utility with a solar electric system, the first step is to review your annual energy consumption (which can be obtained from your utility bill). We are specifically looking for how many kilowatt-hours (kWh) you consume in a 12-month period.

  • How much do these solar power systems cost?

It depends on your electrical usage and your service area. For example a 5kW solar system in Gainesville would remove the majority of a $100.00 per month electrical bill for at least 25 years. Winter months are a little less and summer months a little bit more.

A 5kW Grid-tied system costs approximately $12,250 to install after the 30% Federal Investment Tax Credit. If you were to purchase this solar power system as a business, you would also get a 5-year accelerated deprecation on top of the 30% Federal tax credit.

A solar electrical system protects you from future rate increases and allows you to “fix” your utility rates for the next 30+ years. Systems are designed to lower - or in many cases, eliminate - your monthly electric bill.

If you are a commercial farm, or a business located outside of the City of Gainesville or City of Ocala, there are several grants we can apply for that provide a significant amount of funds to help you transition to solar.

  • How long does it take for a solar system to pay for itself?

This depends on a number of factors: (1) your current cost of electricity (2) the rate structure of your electrical service (3)the incentives available to you (4) and the cost of money on your investment.

When paying cash, a typical residential system may see a simple payback in 8-12 years. If you are financing the purchase of your solar system, you may see immediate positive cash flow, or you may initially see a slight negative impact on monthly cashflow when factoring the cost of the loan against the initial savings. As electrical rates increase, and with your loan payment staying fixed, you will eventually see positive cashflow, a break even point, and then a positive rate of return.

Financed systems typically either see immediate positive cashflow or will attain positive cashflow within three years or so.

  • How long will my solar electric system last?

The main component of a solar system, the solar modules, are typically warranted for 25 years but have a design life of over 40.

There are modules still operating today that were manufactured in the 1970's. The inverters are typically warranted for 10 years. It is not certain how long they may last beyond their warranty period. A conservative set of assumptions when considering the long term financial performance of your system is to figure the performance at 30 years with the replacement of the inverters at year 15. The inverters may represent roughly 5-10% of cost of the system depending on system size, configuration and system installation cost.

However, keep in mind that PV modules are seeing only six to eight hours of active use per day, so we may find that life spans of 60-80 years are normal. Cells that were put into the truly nasty environment of space in the late 1960s are still functioning well. The bottom line? We’re going to measure the life expectancy of PV modules in decades - how many, we don’t yet know.

  • What is the warranty on your installation?

Solar Impact provides a 5-year workmanship warranty, the inverter manufacturer has a 10-year warranty, and the modules carry a 25-year warranty.

  • What does Solar Impact mean by "turn-key"?

Solar Impact will handle every aspect of the project for you, from the system design, filing of the permit paperwork, working with the utility, the installation, and the final inspections. Solar Impact is proud to offer a comprehensive turn-key package to every customer to ensure that installing a solar power system is an easy, pleasant experience for you.

  • Is there any maintenance required?

Because they have no moving parts, they are virtually maintenance-free. Basically, you need to keep them clean. We recommend cleaning them once or twice a year, after the pollen season has ended. All they require is water and a mop or rag. No high-pressure, or soap, or anything else. We do not recommend cleaning them off when they’re hot, since uneven thermal shock could theoretically break the glass. Wash them in the morning or evening. If you do not have the ability or desire to get on your roof and clean your panels, we can recommend a local panel-cleaning business that we hire to clean our panels.

  • Can the homeowner sell power back to their utility?

Yes, through "net metering" any excess electricity generated will spin your meter backwards which has the effect of selling your excess power to the utility at a full retail rate. On a monthly basis, you pay only the "net" of what power you used. If you generate more power than you in a month your utility company will forward your excess solar energy credits to be used during the next month. This allows any excess energy generated in the summer to be used during the winter when there is less solar energy and usually higher energy usage.

  • What are Renewable Energy Certificates (REC)s?

As a solar power generator you are producing power from a renewable energy source -- the sun - which benefits the nation by reducing our reliance on non-renewable sources such as fossil fuels. State governments quantify those benefits in the form of Renewable Energy Certificates (REC)s with one megawatt hour of energy from a renewable source generator being worth one REC.

Currently in Florida, there is no Renewable Portfolio Standard but we believe that will change in the near future. The RECs are part of an incentive program enacted by many states, including New Jersey, Pennsylvania, Delaware, and Maryland, to encourage the development of renewable source energy suppliers. You can learn more about the Portfolio Standard and RECs in your state by clicking on the link to your state above and looking under "Rules, Regulations, and Policies". Under this program, each state enacted Renewable Portfolio Standards (RPS)s which set the minimum percentage of a utility company's power that must be produced from renewable sources. Because there is not enough renewable source suppliers from which the utility companies can buy power directly, they are allowed to buy RECs on the wholesale electricity market to make up the difference needed to satisfy state requirements.

Although there is a ready market for RECs, in reality it is difficult for small producers to sell their RECs outright on the open market because generation can't be registered in units less than 1 REC. Therefore, most small producers sell their RECs through aggregators who combine the kilowatts hours of many small producers and register and sell these as RECs for a commission on the wholesale market.

  • Will a solar system provide power during an electrical power outage?

Most grid tied solar electric systems do not provide electrical power during electrical power outages. As a requirement of a grid tied inverter's safety listing, it must shut down in the event of grid power loss. Backup power systems can be designed into a grid tied solar system with the addition of a battery bank and a battery powered inverter. This option adds complexity and expense that should be weighed against the benefit of having backup power.

  • Doesn't it take a lot of energy to produce solar system?

It certainly costs energy to produce (and mount) a solar panel. Research has shown that after approximately 2 to 5 years the electricity produced by a solar panel equals the energy that was necessary to produce it. This is called the energy pay-back time. Normally, solar panels have a life of 25 years or more.

  • What's in it for me?

Increase your home’s value: Nothing adds value to your home like solar. According to industry experts, your system will add $45,000 to $90,000 to the value of your house. Who wouldn’t want to buy a house that comes with a solar cash machine?

Take control of your power bill: After years of stable electricity prices, nobody knows what’s going to happen next. When you own a solar power plant, you no longer need to worry about rising prices!

Protect the environment and our county: Your solar electric system will reduce greenhouse gases and our dependence on foreign fuels. You’ll feel good knowing that you’re making a difference.
