The last decade has spawned the era of solar panels for home use. Households and businesses around the world are moving from a fossil-fuel power grid to a clean energy economy, necessitated by emission reduction targets in an era of global climate change.
In the midst of this period of energy reform, solar panel systems for homes are taking off at a remarkable rate. It's time to give residential solar the credit it deserves.
Everything you need to know about solar home systems
1. How much has the price of solar energy for residential use dropped in recent years?
If you're an optimist looking for feel-good stats, the cost of solar electricity over the past decade is a great place to start. The cost of solar installation has dropped by around 70 percent in the last 10 years. In the last year alone, the residential market experienced a five percent decrease in cost. There is no doubt that solar energy has evolved from a cleantech product to a reasonable home improvement that millions of people are considering in 2019. Getting solar panels for your home is one of the smartest decisions you can make in the era. current.
2. What is the difference between solar energy for business and solar energy for home use?
A commercial solar project could power a city or business operations. As a result, they vary dramatically in terms of scale and cost. In comparison, residential solar systems tend to maintain a constant size (6 kilowatts on average). Thanks to their relatively small scale, rooftop solar panels for the home are an achievable energy upgrade that can lead to significant savings on electricity bills for homeowners of any income level. On the other hand, commercial solar energy requires a large investment and a collective pool of investors.
3. How much do residential solar panel systems usually cost?
The answer to this question depends on the state and size of the system. However, there is data that can help you estimate the cost of solar panels in 2019. The simplest way to calculate the cost of solar electricity in different sizes of systems is in dollars per watt ($ / W), which indicates how many solar energy dollars Cost per watt of available electricity production. In 2019, homeowners pay an average of $ 2.98 / W. To put that figure in perspective, in 2008 the average cost of solar energy was just over $ 8 / W. For an average 6kW system, a price of $ 2.98 / W means you will pay approximately $ 17,880 before taxes and tax refunds in 2019. (Note: This data belongs to the US, each country has its own)
4. Will my solar panels be connected to the grid? What is net metering?
This will depend on each country. The vast majority of solar home systems will be connected to the grid. With solar power connected to the grid, net metering serves as an efficient solution to the question "How am I going to power my solar home at night?" Net metering is a solar incentive where you receive credits when the solar system produces too much electricity. At times when your panels are not producing enough electricity, you can use those bill credits to cover the cost of using electricity from your network.
If you are not connected to the grid, you will not have access to electricity from your utility company. This means that to build a project completely off-grid, you will need extensive energy storage capabilities, an extra-large solar panel system, and backup power arrangements to cover you when your panels don't get enough sun.
5. How long does it take to install a residential solar system?
Once you've met with the installers and done all the site visits and planning, the actual installation of your solar system at home will only take a few days of work. The exact time depends on a number of factors. For example, if you are setting up net metering, that process will add additional time until your panels are properly connected to the network. In general, while the solar panel decision process may take some time, the installation time is very quick and quite simple.
6. Can you get a solar panel system for your home if your roof doesn't qualify?
Perhaps one of the most interesting aspects of the residential solar sector is the list of options for homeowners who want to use solar energy but do not have a suitable roof. Ground mount solar installations and community solar gardens are two common ways to access solar energy without installing anything on the roof. Community solar power involves connecting with members of a group or your neighborhood to share a solar system, while ground-mounted arrays are an easy way to own and install your own system without going through rooftop obstacles.
7. Does solar power make sense if I don't plan on being in my home for 25 years?
A common concern for homeowners considering solar is, "What happens if I move after installing the solar panels?" A typical solar panel system lasts 25 to 30 years. If you don't plan on owning your home for that long, you may wonder if solar still makes sense. The good news is that solar energy increases the value of your property and can speed up the property sale process when the time comes. The housing market is full of buyers excited about the prospect of acquiring a solar home that comes with the benefit of zero utility bills.
8. What percentage of your home can be powered by solar electricity?
Ideally, the answer to this question would be 100 percent. However, while a solar panel system can theoretically offset all your energy use, it is unrealistic to expect that level of panel production every day of the week. America's leading solar manufacturer, SunPower, recommends a factor of 25 percent to homeowners when calculating their goal for solar panel compensation. The main reason for this: solar panels cannot work at maximum efficiency all the time. There will be certain days when the grid connection is necessary to fully cover your energy use. The good news about network metering, however, is that you can benefit from excess production days and never pay your utility company anything while still relying on the network for backup storage.
9. When will your home solar system “break even”?
Many homeowners are very interested in calculating the payback period for their solar panel, which is the amount of time it will take to save on the electric bill to offset the cost of installing the solar panel. The average expected breakeven point for US homeowners is approximately 7.5 years. For each country it will depend on the costs themselves.
Figures like this illustrate why the residential sector could be the hottest in the solar industry. When installing solar panels for the home, the ROI is high and the payback period can be very short despite the initial cost.
