Solar kits should provide you with the raw materials for building a solar panel system. You may also want to rent a trench digger if you are doing a ground mounted system. Most homes use up around 2kWh of electricity a month. Depending on what percentage of that you want to offset, you will make calculations to determine the number of panels you need. For this example, a typical home average 2kWh electricity will need around 20 panels to offset the entire cost of the system.
Roof mounted systems or single inverter systems can save you money. When you are looking at what materials to buy make sure that they are certified by the underwriter’s laboratory and they are on the list of qualified materials for rebates and solar incentives solar string lights outdoor waterproof
. If you are looking at having the system professionally installed, you are looking at $8 per watt of solar power. The best way to make sure that you are getting the best deal is to get a quote from several different local installers. Compare that price to the price of doing it yourself.
People regularly save 20-25% by doing it themselves. You are mainly saving money in the labor costs as well as sourcing your own solar panels which can save you a great deal. As a reference, a 10 solar panel setup can save the average homeowner 3000kWh in electricity per year. This translates to about $250 of savings per year. This means there is about a 5% return on about a $7, 000 system if you do it yourself. You must also consider that these earnings are income tax free. The savings also go up as the price of electricity will likely rise in the near future. If you’re thinking of building a passive solar house, you need to know some basics about solar houses. There are two types of solar houses: passive solar and active solar. Passive solar structures trap the energy from the sun by using certain house design techniques. Active solar homes also trap the sun’s energy and then collect, store, and distribute that energy using different types of mechanical and electrical equipment. Both types of solar homes use the principles of thermal mass to achieve their goals. Thermal mass is the material, such as concrete or ceramic tile, that holds the solar energy and then slowly releases it. The best thermal mass substance is concrete. Simply building your home using a concrete construction system, such as insulating concrete forms (ICF), provides passive solar benefits.
To provide the energy efficiency that you seek by building a passive solar house, it is vital that the house plans are customized to the geographical location of your building site. After all, the sun’s height and intensity vary depending upon the northern or southern latitude of the home site, as well as the time of year. Generally, in a passive solar house the sun’s energy is collected during the cold months through glassed openings such as windows and doors placed on south-facing walls. A minimal number of windows are used on north, east, or west facing walls to minimize heat loss. This helps to keep the house warm. In hot weather, the sun’s energy is deflected from these opening through the use of roof overhangs, awnings, shutters, or some form of window coverings, thus keeping the home cooler.
