Primary Part Components of a Solar Power Unit for Your Property.

In a framework association body, energy is actually very first created through one or even many sunlight components (likewise referred to as photo voltaic or even PV photovoltaic panels ). A valve change referred to as a separate divides the doors coming from the remainder of the body to ensure that you’ll be actually risk-free if you ever before need to have to perform any type of repair services. Successor is actually the sunlight inverter, which are going to transform the immediate present (DC) coming from the doors in to varying present (A/C) for the house. Coming from the inverter, electrical power relocate to your property buster carton as well as is actually dispersed to the remainder of the house. An electrical power gauge (perhaps various coming from the one you possess currently – with the ability of determining electrical power entering the framework or even being actually drawn coming from the framework) by the end of free throw line are going to gauge the quantity of energy that is actually either needed to have coming from, or even being actually offered back to, the power business. Since our experts’ve outlined the distinct parts of a grid tie system, we’ll discuss what to consider when planning your solar array.

You Will be Living with Your Solar Modules for Years: Choose Wisely.

You first need to need to know a few basic things before you proceed to design you solar energy system. You need to know how much energy you want to produce, how many panels can fit on your roof, and what you can afford to buy. An array can be planned from any of these approaches. Knowing what you consume month-to-month is the best starting place – with this information, you can estimate what size array will produce this energy on a monthly basis, or how much energy can be produced in the space available, or how much energy you can produce with the money you have.

Once you know what your target monthly output is in kilowatt hours (kWh), a little bit of Eighth grade math will let you calculate how big of an array you need. Once you understand this, you can focus on what kind of solar panels you want, where you’ll put them, and how many you’ll need. Look at your utility bills to figure out your daily average use – don’t forget to account for seasonal changes. The average home in the U.S. uses about 900 kWh each month, but this average differs across the country.

You can divide this number by the hours of peak sun hours you receive each day to determine the size of your system. Did we lose you on peak sun hours? Peak sun hours are the number of hours per day anywhere on the planet where the solar insolation (or irradiance) equals 1000watts/square meters. No, you do not need to measure this yourself. You can find this information readily on the Internet for your precise location. You can find out how much sunlight you receive a day on the National Renewable Energy Laboratory website under the "US Solar Resource Map" for photovoltaics.

Let’s take an example. If you use a thousand watts daily, and you receive five hours of sunlight in a day, you’ll need a 200 watt panel to completely cover your usage. In the Southwest, it could be over six hours, while in New England it could be just four hours. The process of comparing your power needs to sunlight availability, load calculation , is crucial to planning your setup.

Let’s take another example using a little more complicated way of getting to how large you need to make your solar array. Take your monthly kWh number (900kWh) / 30 days / month = 30kWh/day. What size array makes 30kWh/day? Now you know that this depends on peak sun, and we will again use for this example five hours. Depending on your location, 30kWh/day/ 5 peak sun hours = 6kW array, or 6,000 watts. For a 6,000 watt (same as 6 kilowatts) array, you would need 30 200-watt panels, or 25 240-watt panels. Most homes that are putting in solar energy can offset most of their electrical needs with an array that is between 4 – 7kW.

Now that you know how much power is needed, you can start designing your solar array. You can choose between two kinds of solar panels: traditional crystalline solar modules, and thin-film solar panels. Crystalline modules are the large solid panels that people usually associate with solar power. They are more expensive, and more efficient, than thin film. Thin film comes on a flexible roll of metal or plastic that can be applied to any flat surface, such as a metal roof. They are much simpler to install, but when roof surface area is an issue, high-efficiency crystalline panels may be a better choice.

Racking Depends on Where you Install the Solar Energy System.

With crystalline panels, you have three options for location: Mounting the panels on your roof, on the ground, or on a pivoting stand. You choose your racking depending on where you plan on mounting your solar energy system.

Most people think that a roof mount is the most convenient and aesthetically pleasing, but there are many reasons that people choose other options: if your roof is small, unstable, or in the shade; if you aren’t able to face the panel towards the equator (facing south in the northern hemisphere and facing north in the southern hemisphere); if you like the simplicity of a ground mount; or if you have extra land. Pivoting stands are an attractive alternative because they are able to follow the sun throughout the day, so they can be far more efficient, but they’re also more expensive. If you have enough open space, a ground mount may be better. With any of these mounting options, you should make sure that there are no local ordinances or homeowners association rules against them.

While most people want to focus on panels and inverters, it’s important to remember that solar panel racks are critical. Besides the orientation and shading issues we discussed above, you also need to find out the wind category in your area as well as your soil conditions if you plan to install a ground mount system. Even with off-the-shelf parts, many permit offices will not give you a permit if the racking approach does not have a civil engineer’s stamp of approval. Solar is still new to a lot of people, including engineers, but solar racking systems are in essence just giant erector sets and getting an engineer’s approval of a proposed structure is often required. You should be able to hire an engineer for $500 or even less.

Solar Inverters Are a Critical Component to your Solar Energy System.

Now, having chosen your solar modules, you’ll need to decide on a solar inverter. Again, the inverter changes direct current (DC) from the panel into alternating current (AC) that your appliances can use. There are several considerations here. First, you’ll need to make sure to choose a grid tie inverter rather than an off-grid inverter. Second, you need an inverter that can handle what your panels generate, so make sure the wattage of the inverter is as strong as the wattage of your array. Third, you can consider solar micro inverters , smaller inverters that are connected to each panel instead of the entire system as a whole.

Other Balance of System Components.

After selecting panels and an inverter, the rest of the system (known as balance of system , or BOS) is simple to plan. You’ll need to contact your local utility about the metering system – in most cases, they will give you the two-way meter (also known as a "net meter") for free. You can also consider a battery backup . For safety reasons, solar inverters will shut off current in a blackout, even if the array is making power, so that linesmen aren’t zapped by errant solar systems while making repairs. If you install a backup battery bank, you can power critical loads independent of utility power. This requires specific wiring from the battery to the critical loads, but enables you to have power if the grid goes down. PV systems with battery backup are considerably more expensive.

Economic Incentives Will Lighten the Financial Burden.

Now that your system is planned, you only need to figure out installation, solar financing for your solar power system, and other various legal issues. First, stop by Database of State Incentives for Renewables & Efficiency (DSIRE), an up-to-date database of energy efficiency incentives. The United States government will provide a 30% tax credit for eligible costs of your solar array, and you can find more grants, loans, and tax credits from your state or local government. DSIRE also has information on utilities that will buy electricity back from you. While you are reviewing this material, keep in mind that some incentive programs limits the benefits to those systems installed by an approved installer and are not available to those who install the system themselves, so be clear on the eligibility requirements of any programs you investigate.

There may be other incentive programs such as the Property Assessed Clean Energy Programs. At SolarTown, we will be launching a special solar financing program to allow you to defer payments on your purchase for up to one year. Please contact us for more information.

Now all you need to do is plan your installation or you may choose to select a solar energy installer through Cooler Planet. If you do install the system yourself be sure to read our DIY solar installation tips!, Make sure to hire a licensed electrician for a safety inspection, or for just helping with wiring challenges Electricians are licensed and can pull permits with your local building office. More importantly, you can install your system all the way into your breaker box, but it will need inspection. Do not install a solar energy system without obtaining the permits required by your local government authority. Your local laws may require this, and other safety measures such as building permits, so be sure of these things before you begin. Once you’re sure you’re in the clear, you can start building!
