The dataset comprises measured PV power generation data and corresponding on-site weather data gathered from 60 grid-connected rooftop PV stations in Hong Kong over a three-year period.
The total installed capacity of installed rooftop PV for 2023 reached 2.9 GW from 314,507 units, surpassing the level of commissioned large-scale generation projects in 2023 (2.8 GW). Additionally, rooftop PV reached a major milestone in March 2023, surpassing 20 GW of total installed capacity across the country2.
Thanks to the unprecedented solar capacity growth in 2023, a record-breaking 473 GW of renewable power capacity was built worldwide – a 54% increase from 308 GW in 2022. The strong growth in 2023 brought the world closer to achieving the ambitious goal of tripling renewable capacity by 2030.
The report, developed with data provided by solar consultancy SunWiz, has also found that rooftop solar photovoltaic (PV) system installations reached 20 GW of total capacity across Australia in 2023. New South Wales broke the record for the highest annual installed capacity of any state, with 970 MW of new rooftop solar systems.
Almost three-quarters of all renewable capacity built in 2023 was solar. Wind additions also increased by a sizable 51% in 2023, accounting for another quarter of renewable capacity additions in 2023. After two years of slower growth, 2023 saw a new record for wind capacity additions, beating the previous record set in 2020.
Solar capacity additions surged 74% in 2023, reaching a record 346 GW annual additions. China was the key driver behind the acceleration but solar's phenomenal growth is spreading globally, with 28 countries installing over one gigawatt of new capacity in 2023.
Power generation from solar PV increased by a record 270 TWh in 2022, up by 26% on 2021. Solar PV accounted for 4.5% of total global electricity generation, and it remains the third largest renewable electricity technology behind hydropower and wind.
The average cost of a residential solar panel system ranges from $18,000 to $43,000, depending on the system size, location, and available incentives.
The average pre-incentive cost of home solar is $29,161 for a three-bedroom house, or $20,412 after claiming the 30% tax credit. However, as shown in the chart below, the number of bedrooms isn't a great indicator of the size and cost of a solar system – and neither is living space, for that matter.
A basic home 2kWh solar generator will cost you between $1,600 and $2,000. You could probably power a couple of appliances, keep lights on and recharge devices with a 2kWh solar generator. Our favorite 2kWh solar generator is the BLUETTI AC200P - or upgrade to the AC200MAX, which can be extended by adding additional power packs.
The average national cost for a 5-kilowatt system ranges from $14,000 to $20,900, depending on the source and period of data. EnergySage reports that the average cost of a 10.8 kW solar panel installation is around $29,926 before federal tax credits, which reduces to $20,948 after the credits are applied.
The cost per watt is what you pay for each unit of power of your solar energy system. Think of it a little like “price per square foot” when you buy a house. It helps compare the value of solar energy systems in different sizes. As of publishing, the average cost per watt is $2.84.
Good examples include the 6kWh Goal Zero Yeti 6000X, the 4.8kWh Renogy Lycan 5000, and the 5.1kWh BLUETTI EP500. Expect to pay $5,000-$8,000 depending on accessories, grid-tie equipment, and solar panel choices. Pre-configured solar generators that can store more than 6kWh of energy are expensive and relatively new.
These include maintenance, repairs, and insurance costs, which are essential for ensuring the longevity and efficiency of your system. According to studies by Fraunhofer ISE and HTW Berlin, these operational costs are estimated at around €26 per kWp annually. For a 10 kWp system, this translates to approximately €260 each year.

The Ivanpah Solar Electric Generating System has significantly impacted the Mojave Desert ecosystem, particularly the threatened Mojave desert tortoise (*Gopherus agassizii*). Initially anticipating only 30 tortoises on the site, developers encountered over 170, prompting large-scale relocation efforts.
The plant can be a startling sight for drivers heading toward Las Vegas from Southern California along busy Interstate 15. Amid miles of rock and scrub, its vast array of mirrors can create the image of a shimmering lake atop the desert floor, but depending on the angle of the sun and mirrors, it could also be blinding.
Fields of heliostat mirrors focus sunlight on receivers located on centralized solar power towers. The receivers generate steam to drive specially adapted steam turbines. For the first plant, the largest-ever fully solar-powered steam turbine generator set was ordered, with a 123 MW Siemens SST-900 single-casing reheat turbine. [ 19 ]
California, driven by its Renewable Portfolio Standard (RPS), began pushing aggressively for renewable energy sources, setting ambitious targets that mandated utilities procure a large percentage of their electricity from clean sources. This provided fertile ground for a revived effort in concentrated solar power.
Final approval for the project was granted in October 2010. [ 24 ] On October 27, 2010, Governor of California, Arnold Schwarzenegger, Interior Secretary Ken Salazar, and other dignitaries gathered in the Mojave Desert to break the ground for the construction.
