This is what you pay for when you buy energy from the local utility company. A kilowatt-hour (kWh) is a unit for measuring energy. It is, as its name suggests, one kilowatt of power used over a period of one hour.
If properly installed, it should last 30-40 years. Systems that were installed in the 1970’s are still fully operational today. Technology has evolved so the systems from the 1970’s may not be as efficient as today’s technology.
With systems that we recommend, very little. PV systems are inherently very low-maintenance, requiring the system owner only to wash the solar modules down with water when they get dirty so light can get through.
Right now the US has to import oil and natural gas to cover our energy needs. The cost adds up to many billions of dollars, and all of that money leaves the country. Solar energy is generated locally. Moxie Solar installs panels that are made in the U.S. The energy dollars stay at home, creating economic growth and benefiting your community. Solar power also offsets the total consumption of fossil-fuels, which benefits everyone through the laws of supply and demand.
Currently, the US depends on fossil fuels, especially oil, from potentially unstable or unfriendly countries. These supplies are vulnerable to political upheaval, trade disputes, embargoes, and other disruptions. In 1973 we imported only about 34% of our oil, and yet the 1973 oil embargo was a serious blow to the economy. Today we import over 53%, and are more vulnerable every year. Solar energy can help reduce this dependency, making our economy, our nation, and our families more secure.
It reduces your energy bill, and in many cases the utility company will buy back any extra electricity you generate. Federal, state, and utility financial incentives are available in many areas. It adds to the value of your home. You gain energy independence. Perhaps most importantly, it’s a good investment in a sustainable future for yourself and your loved ones.
Usually not. An HOA may try, but in many states, this is not allowed. However, HOAs may ask you to modify the design and/or location for aesthetic reasons as long as the changes don’t significantly impact solar electricity production (a decrease greater than 10%) or cost more than $2,000.
In general, we recommend that your roof be less than 15 years old if you decide to go solar. Your home solar system will last for twenty years or more, so you’ll need to have at least twenty good years left on your roof. If your roof needs to be replaced or repaired, it’s best to do so before you get solar, so you don’t have to remove and re-install the panels later on. However, it is possible to do a roof replacement or repairs once you have solar.
If your roof isn’t optimal for solar and you have ground space, you might choose a ground-mounted solar system. People commonly choose ground mounted systems if the roof doesn’t work (faces the wrong direction, made of the wrong materials, etc.) or if they have a lot of space on their property. Moxie Solar offers best-in-class ground mount systems that are durable and reliable.
PV systems can be designed to generate the majority of the electricity used in your home, or just a portion of it. In general, your solar system will not be designed to offset 100% of your electricity needs. This is because it makes more financial sense to get some of your electricity from solar energy and the rest from your utility company (i.e. in the daytime, solar electricity is bountiful but utility electric rates may be at their peak; at night, your system won’t produce any solar energy, but you can use cheaper, off-peak electricity from the utility company). For a Midwest example, the average residential home uses approximately 720 kWh of electricity per month. A 3.5 KW PV system would offset more than half of the average household’s electricity…
