Solar energy encompasses far more than just rooftop PV panels — multiple technologies convert sunlight into usable energy in different ways. The main solar technologies are photovoltaic (PV) for electricity, solar thermal for heat, concentrating solar power (CSP) for utility-scale generation, and emerging tech like perovskite and agrivoltaics.
Photovoltaic (PV) Technology
The most common solar technology, PV cells convert sunlight directly into electricity via the photovoltaic effect. Modern cell types include TOPCon, HJT, and IBC, each offering different efficiency and cost tradeoffs.
Solar Thermal Technology
| Technology | Use Case |
|---|---|
| Flat plate collectors | Residential water/pool heating |
| Evacuated tube collectors | Higher-efficiency water heating |
| Concentrating Solar Power (CSP) | Utility-scale electricity generation |
Concentrating Solar Power (CSP)
CSP uses mirrors to concentrate sunlight, generating heat that drives a turbine — unlike PV, CSP can pair with thermal storage for dispatchable power after sunset.
Building-Integrated Photovoltaics (BIPV)
BIPV integrates solar generation directly into building materials — solar shingles, facades, and windows — blending aesthetics with energy production.
Emerging Technologies
Perovskite tandem cells, agrivoltaics (combining solar with farming), and floating solar (floatovoltaics) represent the next wave of solar innovation, each addressing different deployment constraints.

Frequently Asked Questions
What are the main types of solar technology?
Photovoltaic (PV), solar thermal, concentrating solar power (CSP), and BIPV.
What’s the difference between PV and solar thermal?
PV generates electricity directly; solar thermal captures heat for water/space heating.
What is CSP used for?
Utility-scale electricity generation, often with thermal storage for dispatchable power.
What is BIPV?
Building-Integrated Photovoltaics — solar generation built into materials like shingles and facades.
What is agrivoltaics?
Combining solar panel installations with agricultural land use.
Is perovskite solar technology available yet?
Mostly in research and early commercialization — not yet mainstream for residential use.
Which technology is best for residential solar?
Standard rooftop PV remains the most practical and cost-effective for most homes.
