Common Questions Asked About Solar

Fitting your home with a solar system is a big decision, involving significant expenditure.
Below, we answer the common questions most people ask about solar power.

1. How much does a solar system cost for a house?

Of course, there are a number of factors that go into the cost of residential solar systems. Namely, where you live, how much does electricity cost where you live, and how much power do you want to generate.

First, it is important to know the cost of electricity in the state you live in. Electricity is priced differently from state to state in the United States. For example, electricity cost more in the northeast as compared to somewhere like Florida where cost for electricity is one of the lowest in the nation. This can impact the price of a residential solar system significantly. The cost of electricity is determined by the cost per watt. It is therefore important to get comparative costs for solar panels and complete residential solar system installations in the area you live.

In Florida presently, the cost per watt is $2.96. A solar system can generate two thousand kilowatts or it can generate one hundred thousand kilowatts. It simply depends on how much electricity you want to generate. The cost of your solar system will obviously be more the larger your solar system is because it will take more equipment and more time in labor to install it. As of January 2020, the average sized solar system installation in the United States is $11,411 to $14,874 after solar tax credits. The investment tax credit (ITC), also known as the federal solar tax credit, reduces your solar system installation cost by 26 percent. You may also be eligible for state, local and utility financial incentives that could reduce your solar system cost even more.

Solar technology is improving every day which will make solar systems more efficient and less expensive. You should also keep in mind when analyzing costs that solar energy once set up saves you money on electricity and gas. Solar power is definitely economically sensible in the long run.

2. What are the different types of solar panel systems?

The main types of systems that are used by people in their homes are photovoltaic and solar heaters. The first uses sunlight to create electricity, the second uses it to heat water. There are three types of photovoltaic systems: stand alone, grid tied and remote battery. These photovoltaic systems can vary in terms of cost and performance.

Stand alone photovoltaic systems produce power only when the sun is shining. The power it generates cannot be stored for later use and can only be used sporadically. This system is not appropriate in most cases because most people want power available 24/7.

Like stand alone systems, grid tied systems generate solar energy when the sun is shining too. However, unlike stand alone systems, when power is not generated, grid tied systems can pull power from the grid. In addition, if your solar system generates power exceeding your demands you can sell that excess power back to the grid.

Remote battery powered systems can be a good choice because the energy generated is stored in batteries that can be used at any time. A combination of these three systems could be the optimal solar system for you.

3. Can I install a solar system myself?

Yes, if you have experience and confidence in design, construction and electrical systems, of course you can. However, in some geographical locations, governmental regulations require solar system installers have appropriate knowledge and training.

4. How long do solar panels last?

Photovoltaic systems that convert solar energy to electricity can last over 30 years, while solar heaters have a typical lifespan of 15 years. There is typically a 25 year warranty on photovoltaic solar panels. The solar panels don’t stop producing electricity after 25 years. Their energy production declines to the point where manufacturers consider it to be a significant amount.

5. Will solar power ever become obsolete?

While we can never say never, the solar industry is expected to boom over the next few decades. All indications predict that solar will take off as an ideal choice to power homes and businesses all over the world.

There are many reasons for this. Solar is totally clean and eco-friendly. It is safe and it is a sustainable and renewable source. There is no doubt that solar power will continue to grow in popularity, especially to power residential homes.
