Though it’s up to every individual to decide how to invest hard-earned funds, residential solar systems afford individuals access to abundant energy from the sun’s rays. With a residential solar payback time of fewer than four years, this converts into an easy, on-paper investment return of nearly 10 per cent per year. That much money adds up, even when spread out over several decades. But residential solar systems sizing isn’t just about figuring out how much it will cost.

Considerations

When it comes to residential solar systems sizing, three primary factors should be considered. These factors are the purchase price of the equipment, the installation price of the equipment, and the set up fee or labour costs. The upfront costs of these components can often be a significant deterrent to purchasing a system. For instance, buying a one-watt-per-day panel for your entire home can cost in the neighbourhood of ten thousand dollars or more.

Fortunately, new developments in residential solar technology have made it possible to shrink this price tag. Now, new residential solar systems can deliver big savings that approach the cost of a comparable non-solar energy system. One popular method called “photovoltaics” or PV makes use of a collection of photo-cathode cells (or PV cells) to generate electricity. Another method called “pico-systems” or “solar PV systems” make use of individual photovoltaic panels to generate smaller amounts of electricity. Either method has the potential to scale back the cost of a residential solar installation by as much as 90 per cent!

Solar Systems

Today’s residential solar systems make use of multiple, tightly-knit components to take advantage of each part of the solar cell. By marrying the efficiencies of several parts, the combined output from PV cells can greatly amplify the overall efficiency of a solar cell. This output is then amplified many times over by careful design and wiring. Together, the PV cells produce the electric charge needed by a homeowner or business owner to power their electrical appliances, lighting systems, security lighting, air conditioning, and even computers and cell phones.

The PV cells are connected either together in a single solar array or connected in series. In a single array, panels are placed on just one side of a roof. By mounting the panels on just one side of the roof, the amount of sunlight available for conversion into usable electricity is maximized. Connecting the panels in series allows several smaller PV cells to be installed in the “loops” on different sides of the roof. Each loop can switch sources of electricity when necessary and handle a higher demand during peak evening hours. This ability to “pre-load” means there will never be a moment when the electricity needed from the local utility company is lower than the amount the solar system can supply.

Equipment

Residential solar systems come with a controller that monitors the amount of electricity being used and adjusts the amount of electricity required by the system. As more energy is needed by the system, the controller adjusts the amount of energy needed until the desired daytime electricity level is achieved. The number of kilowatts the system can handle will vary depending on the size of the solar system and the location it is located in. It is best to visit your local utility company and get an estimated number of kilowatts that your residential system can handle before considering any additional equipment to increase the system’s ability to store energy for future use.

Although residential solar panel systems can cost up to several thousand dollars, they are well worth the investment, as they will allow the user to significantly save money on their electric bills. The cost of a residential solar system is significantly less than paying the electrical company a monthly fee every month. Residential solar panel systems can often pay for themselves within the first year of ownership.

As residential solar panel systems continue to improve and become more affordable to the general public, more people can take advantage of them. With the cost of kilowatt charged by the electrical company steadily rising, the addition of a solar panel system can be very beneficial to anyone who wants to help reduce their cost of living. Although residential solar panel systems will not eliminate the cost of electricity, they will greatly reduce it, especially if solar panels are placed on the home’s roof.…

Solar panels do not come falling from the sky, no matter how hard they are made to appear. Similarly to other electronics, this also is an energy-efficient and dirty process. It takes a lot of effort in the initial stages, even before you can get your hands on the materials you need. Besides, once you start putting them together, it will still take some time to make sure that you have all the tools and equipment that are required to properly install them.

If your home is currently consuming high quantities of electric, you may find that you are paying much more for electricity than necessary. You are probably aware that most countries are experiencing energy shortages at the moment. This has lead to high retail prices and some people are even losing their jobs, as companies are downsizing and closing down because they are unable to cope with the economic climate.

Installing Solar Panels

The good news is that by installing solar panels on your property, you can save a lot of money on your electricity costs. Even if you can generate enough energy to power your entire household, it will still not cost you much. Therefore, our solar panels worth it? In most cases, yes. However, there are various factors that you need to take into consideration before deciding whether or not solar panels are the right option for you.

One of the first things to consider is the worst-case scenario. Do you think you would be able to handle a major blackout? In the worst-case scenario, your electric company will not be prepared to offer you alternative sources of electricity. This means that you would have to rely on your solar panels. If you are unable to generate the maximum amount of electricity, you could even be left without electricity for days, especially if your solar panels are located in the desert or the worst-case scenario, the coastal areas.

Another thing to consider is power density. If you are trying to generate enough energy to power your entire household, you should realize that it will take a very long time. Solar panels can only deliver a maximum output of power at an annual rate of less than 1% per year. To make up for this power generation gap, you will have to buy back power from your local electric utility. This is referred to as net metering and it can help you pay for the cost of installing and operating solar panels.

Benefits

Now, let’s say that solar panels do reduce your electricity bills, but that you are also attempting to limit your use of fossil fuels. Net metering only helps you if you are using no more electricity than you are consuming. For example, if you are using coal to heat water, then you are consuming a lot more electricity than you are producing. This means that while you are paying the power company for electricity, you are in essence causing more greenhouse gas emissions than you are using. The opposite scenario would be to heat water using solar cells and then to store it in solar cells using a solar tank.

Net metering can give you both of these benefits if you are careful about what your consumption is. If you are trying to save the most money, you should try to consume as little electricity as possible. If you are attempting to reach power independence, then you are going to need to consume a larger portion of your household energy consumption. For this, solar panels are not your best bet.

Hopefully, you now understand why solar panels are not your best bet for reducing your energy bills or even achieving energy independence. They are a great way to cut your costs, but they are not a good way to do it. Rather, you should be trying to increase your energy savings, while reducing your use of fossil fuels. You can accomplish this quite easily by making your appliances run as efficiently as possible. Also, you can take advantage of tax credits and rebates available to you, if you are a United States taxpayer.…
