Solar panels settings

Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis. It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air.

How to install solar panels: five main steps.

There are five major steps to a solar installation that your chosen solar company will generally follow: 1. Engineering site visit 2. Permits and documentation 3. Ordering equipment 4. Solar panel installation 5. Approval and interconnection 1. Engineering Site Visit. The first step to getting your solar system installed After you sign your solar contract (whether it be a lease, loan, cash purchase or power purchase agreement), an engineer will come by your property to evaluate the electrical status of your home and ensure everything is compatible with your new energy system. This engineer will typically work directly for your installer, but could also be an independent provider contracted by your installer. You can expect the engineering site visit to occur soon after signing with your installer. During the visit, the engineer will evaluate the condition of your roof to ensure that it’s structurally sound. He or she will also look at your electrical panel – the grey box in your basement – to see if you’ll need to upgrade it. If you hear from an installer that they need to upgrade the electrical panel, that means that your new solar panels will require more amps of current and the ampere capacity of your electrical box will need to increase. It should be noted that this engineer visit is different than a general site visit which is when an installer evaluates your property to consider system size, roof type, angle of roof, shading, etc. before any contract is signed. Additionally, though an engineer will typically come by, in some cases the installer can take photos of the property and conduct their own measurements of the roof and the engineer will be okay with signing off without doing his or her own visit. 2. Permits and documentation The logistical paperwork required for your solar panel installation As with any big financial decision, installing solar panels involves a lot of paperwork. Luckily, most of this paperwork is dealt with by the installer – regardless, it’s always a good idea to know what’s going on behind the scenes of your solar installation. One of the main things you’ll be applying for will be state and federal solar incentives such as the federal ITC, local solar programs, clean energy financing initiatives like PACE, government rebates and solar renewable energy certificates (SRECs). In addition to applying for incentives, you will need to fill out other paperwork like building permits. These permits are specific to where you live. For example, certain states require that a roof has three feet of clear space surrounding the solar panels, whereas other areas of the U.S will allow you to install panels across the entire surface of your roof. Your installer will know the restrictions and requirements of the states in which they operate, and can help you figure out which permits you need – in many cases, the installer will fill out this paperwork for you. The time frame for this step is mainly dependent on how long it takes your installer to get it all finished and submitted. If you’re eager to get your panel system up and running immediately, just make sure to follow up with your installer to check on the progress of your paperwork. 3. Ordering equipment Choosing the panels and inverters and getting your solar panel installation scheduled solar installer talking to homeowner Now that you’re set up with the proper paperwork, your installer will be ready to place an equipment order through their primary distributor. At this point, you will have already decided on the equipment your system will include – that decision occurs before the contract sign. However, if you’re looking for advice on equipment selection, here are some things to consider. The two primary components you’ll need to evaluate for your system are solar panels and inverters. Your installer will likely recommend a particular brand for each, and will additionally offer a few alternatives. Durability, efficiency and aesthetics are the primary factors most homeowners will use to compare the various brands (other than price). To be certain that you’ve chosen the right equipment for your system, spend some time researching microinverters vs. string inverters vs. power optimizers and look into the best-rated solar panels on the market. Evaluating your equipment options can help you feel prepared for the ordering and shipment stage of the solar panel installation process. Once the equipment ordering process is complete, your property is added to your installer’s queue.Your equipment (panels and inverters) will likely arrive on the day of your installation, which can happen whenever your paperwork is approved (typically within one to two months). Time until install also depends on how many projects your installer has in their queue. If possible, try to get your solar installation done in the winter when solar companies aren’t as busy. 4. Solar panel installation The actual installation is an exciting day for every solar homeowner. Your solar installer will start by prepping your roof and making sure the shingles or tiles are properly attached. Then, they put in electrical wiring that will connect to your electrical panel and general power system. After the electrical wiring is complete, they will install racking to support your panels (this is the only piece of equipment that will actually be attached to your roof). Once the racking is level and safely attached, the panels are placed onto the racking. Finally, your inverter(s) are connected to the panels to convert direct current (DC) energy into the alternating current (AC) energy used in homes and on the electric grid. The timeline for the installation will range from one to three days, completely dependent on the size of the system you are installing. One additional factor that can add time to your installation process is putting in a power meter for net metering. If your installer needs to add a power meter, this will add a few hours to your solar panel installation. 5. Approval and interconnection Before you can connect your solar panels to the electric grid, a representative from your town government will need to inspect the system and give approval. During this inspection, the representative will essentially be double-checking your installer’s work. He or she will verify that the electrical wiring was done correctly, the mounting was safely and sturdily attached, and the overall install meets standard electrical and roof setback codes. Following this local inspection, you will be ready for official grid interconnection. A representative from your electric company will come by to do their own final evaluation of the solar panel system. As long as there are no glaring issues, your panels will go live the moment they “give the okay” and connect your system to the grid. You can expect to wait two weeks to a month for the town approval and utility approval to occur and interconnection to go live. Why go through the one to three-month process of installing solar on your home? In 2020, the average solar shopper on offsets approximately 94% of their electricity usage by going solar, and will pay off their solar energy system in just under 8 years.
