There are two key ways to harness solar energy: photovoltaic (PV) and concentrated solar power (CSP). Countries such as China, Germany, Spain, and the United States (U.S.) have some of the largest solar resources all over the world. Solar power is the cleanest and most plentiful renewable energy source present on this planet. The sudden rise in CAGR is attributable to this market’s demand and growth returning to pre-pandemic levels once the pandemic is over. The market is expected to grow from USD 184.03 billion in 2021 to USD 293.18 billion in 2028 at a CAGR of 6.9% in the 2021-2028 period. Based on our analysis, this market will exhibit a stagnant growth of 4.18% in 2020 as compared to the average year-on-year growth during 2017-2019. The global impact of COVID-19 has been unprecedented and staggering, with solar power witnessing a negative demand shock across all regions amid the pandemic. Alternatively, if you can't afford to purchase your panels, you can choose to rent them (but you won't qualify for tax credits and incentives).įiguring out the number of solar panels you need is only part of the equation.The global solar power market size was USD 170.55 billion in 2020. For instance, the federal government provides a tax credit on new solar installations, and many state and local governments offer rebates or incentive programs. Key points to keep in mindĪlthough the upfront costs of a residential solar system might seem high, there are a few ways to save money on your investment. Assuming that your energy usage is in line with the average of 29 kWh per day, you'd need 23 325-watt panels to create enough electricity for your home. In that case, each panel can generate 1,300 watt-hours per day (or 1.3 kWh). Let's say that your property receives four hours of sunshine each day, and you're purchasing 325-watt solar panels.
In this example, we'll use the average annual energy consumption, solar panel wattage and hours of sunlight that we mentioned earlier. With those variables in mind, we can roughly estimate the number of solar panels for home that you'll need.
