The Grid-Connected PV System

We all know that solar energy systems are beneficial, but there are a few things to think about when considering a grid-connected PV (photovoltaic) system. Benefits of a Grid-Connected PV System Off-the-grid renewable energy systems are able to completely power a home. However, connecting to the power grid can offer a wider variety of benefits. One of the benefits is the ability to draw electricity from the utility company when solar power is not enough. Some power providers allow a net metering agreement by using a single meter to track the amount of excess electricity that is fed back to

The Solar Water Heater

The solar water heater works by using the sun’s energy to heat water or a heat-transfer fluid. The solar collector and insulated storage tank make up these systems. In the case of a one-tank system, two sets of outlets and inlets circulate water through the tank and the heat transfer liquid through the water. Two-tank systems work in a similar manner but the water is preheated with solar energy before it enters a conventional water heater. The Different Types of Solar Collectors The solar collector is the component of a solar water heater system which harnesses solar energy and transforms

Planning a Home Solar Energy System

There are several factors you should take into consideration when planning a home solar energy system. Do you have enough clear access to sunlight for extended periods of time, both during the day and throughout the year? You also want to determine the size of your future system, and whether you have the surface area to sustain it. The natural questions then follow: “Is the investment worth it? Will the system generate enough energy to offset the costs in a timely manner?” Finally, you have to take into account the legal situation regarding solar panels in your area. This means

Rebates and Incentives for a Solar Power System

Taxpayers can claim a 30% federal tax credit on qualified expenditures for a solar power system. The credit has been extended until December 31st, 2021, but will be reduced to 26% in 2020, and 22% in 2021. Whether it is a solar panel system or a solar water heating system, qualified expenditures include equipment and labor costs. Equipment expenditures are calculated after the installation is complete. A credit for labor costs is only available if the system is installed by a professional. Solar Panel Systems The home with the installed solar power system doesn’t have to be the taxpayer’s principal

The Basics of Solar Energy

Did you know that more solar energy reaches the earth in one hour than is used by the entire world in one year? Harnessing this energy has been a focus of research for many years. Today we can find the benefits of this research in many systems, ranging from photovoltaic solar systems to solar water heaters. In fact, we’re seeing solar power being utilized now more than ever. This popularity is due to the constantly improving technology, decreasing costs, and government incentives. As a result, solar power is being used everywhere. Homeowners use solar power to help cover a big part, if

What is a Photovoltaic System?

Photovoltaic (PV) systems use solar modules, also known as panels, to turn the sun’s energy into electricity. A single PV cell typically produces 1 or 2 watts of power by itself. PV cells are connected together in chains to boost their power output. These chains of cells are called modules or panels. When several modules are linked together they are called an array. A complete photovoltaic system consists of one or more arrays connected together as well as several other elements which facilitate the transformation and transmission of electricity. Mounting Structures A photovoltaic system requires a durable, stable structure that supports

How Much Do Solar Panels Cost?

One of the first considerations when thinking about going solar is the cost. This leads to many other issues such as monthly savings and your return on investment. It all depends on the type of system you need for your home. Residential solar systems can range in output from 3kW to 8kW and the price tag on such a system can range from $15,000 to $40,000. With that being said, the cost per watt, which includes labor, parts, overhead, and permitting fees, has decreased considerably, and nowadays you can expect it to be $6-8/W. In most cases, the bigger the

HOA Restrictions on Solar Panels

Going solar requires a certain degree of planning. Consideration of HOA restrictions for solar panels is certainly a part of it. Once you’ve decided on the solar panels you’re going to use, the power output that you expect to have, your rebates, and financing options, you’re left to gain approval from your homeowner’s association.  Sometimes dealing with your HOA can be a headache. When it comes to solar panels, however, you have clear legal guidelines on what restrictions your HOA can place on your solar panel project in Texas. In fact, the law is on your side. According to House Bill
