These ultra high-efficiency solar cells use advanced materials like perovskites and multi-junction cells with multiple layers that can absorb and convert more of the sunlight into electricity.
Commercial solar panels in 2024 now commonly reach efficiencies over 20%, with top models from companies like SunPower, LG, and Panasonic exceeding 22% efficiency The 11 Most Efficient Solar Panels 2024. That’s a major increase from typical 15-18% efficient panels just a few years ago. These gains in efficiency allow homeowners and businesses to produce more solar energy from the same amount of roof space.
Improved Manufacturing
The manufacturing of solar panels is expected to improve significantly in 2024. One key innovation is the use of roll-to-roll processing which allows solar cells to be printed onto flexible plastic substrates (https://www.technologyreview.com/2024/01/08/1085124/super-efficient-solar-cells-breakthrough-technologies/). This method is faster and cheaper than conventional solar panel manufacturing. Additionally, 3D printing technology is being adapted for solar panels, enabling more versatile panel shapes and sizes to be created. This allows panels to be customized to fit the exact needs of different applications.
For example, researchers at Stanford University have developed a 3D printable solar ink that makes it possible to 3D print photovoltaic generators in almost any shape (https://www.nexamp.com/blog/the-future-of-solar-energy-trends-and-predictions-2024). With precise 3D printing, solar panels can be formed to seamlessly integrate with curved surfaces on vehicles, aircraft, and buildings. Overall, advanced manufacturing innovations will drive down costs and expand the use cases for solar power generation.
Lower Costs
One of the biggest developments with solar panel technology in 2024 is significantly lower costs. Solar panels in 2024 benefit from economies of scale, as increased production volumes have enabled manufacturers to achieve lower per unit costs. The solar industry has also seen innovations in manufacturing techniques and the use of cheaper materials, further reducing expenses.
Whereas solar panels were previously seen as having high upfront costs, the steep drop in prices over the last decade has made solar energy cost competitive with fossil fuels. Continued declines in solar panel pricing in 2024 increase adoption by making the return on investment more attractive for homeowners and businesses. Tax incentives and solar leasing options which spread out upfront costs over time also assist with affordability.
The lower price point broadens the accessibility of solar technology in 2024. Solar energy transitions from an option only suitable for affluent customers to a viable energy solution for middle and working class families. More homes and businesses can now benefit from zero fuel cost, clean energy generation.
New Form Factors
In 2024, there are exciting new form factors for solar panels coming onto the market. Two of the most innovative are flexible solar panels and solar shingles.
Flexible solar panels allow panels to be installed on curved surfaces like car roofs, tents, and rounded building facades. Companies like Sunflare are producing lightweight, flexible CIGS (copper indium gallium selenide) solar panels that can be applied like stickers to unconventional spaces. According to research from Tongwei, flexible solar panels will increase adoption of solar technology in new environments like vehicles, clothing, and consumer devices.
Solar shingles, like those produced by Tesla’s Solar Roof system, integrate solar cells directly into roofing shingles. This allows a home’s roof to simultaneously generate solar energy while also providing protection from the elements. Solar shingles can reduce installation costs and provide an aesthetic advantage over traditional bulky solar panels. Industry forecasts predict wider adoption of solar shingles in 2024 as more integrated and affordable options become available.
