FAQs about Solar photovoltaic simulation equipment price
How much does a solar simulator cost?
Solar simulator B has a capital cost of $35k — slightly lower than the LED solar simulator because xenon arc lamp solar simulators have been in the market longer. Xenon arc lamps have a much shorter lamp lifetime of 1,000 hours and an approximate bulb replacement cost of $1,600 (including the time to install and test a new bulb).
What can I do with a solar simulator?
You can also use a solar simulator to study photobiological systems, material exposure to sunlight, and many other applications. We offer a low-cost, highly versatile solar simulator, that you can use either as a standalone system or with our I-V test systems to form a complete solar cell testing kit.
How much power does a solar simulator a use?
Solar simulator A consumes 0.6 kW of power. If we assume nominal costs for electricity ($0.174/kWh) we get a total power consumption per year of about $150, or $1,500 over a 10-year period. With these values in mind, we can calculate an approximate total cost of ownership (TCO) for solar simulator A over a 10-year period.
What is a Flash solar simulator?
Flash solar simulators use a flash lamp and spectral filter to deliver a pulse of light onto a target for a short period, with minimal heating of the sample and lower cost per target area. Sciencetech manufactures a wide range of flash solar simulators.

Spectral Coverage (SPC): This is the percentage of the sun's spectrum that is covered by a solar simulator's output. If a solar simulator only emits light from 450 nm to 1050 nm (rather than 400 nm to 1100 nm), the solar simulator would have a rough spectral coverage of 86%. A higher spectral coverage is better.
Should you buy a solar simulator?
A solar simulator is just one tool in the arsenal of instruments needed for research and when making a purchase decision, a group must consider the cumulative cost of all their instruments. Over the long turn, savings in one area can offset higher expenses in other areas or enable wider resource allocation to other projects.
