2. Thermophotovoltaic energy conversion - Wikipedia

   en.wikipedia.org/wiki/Thermophotovoltaic_energy...

   Solar TPVs are a source of emission-free renewable energy. TPVs can be more efficient than PV systems owing to recycling of unabsorbed photons. However, losses at each energy conversion step lower efficiency. When TPVs are used with a burner source, they provide on-demand energy. As a result, energy storage may not be needed. In addition, owing ...

3. Off-the-grid - Wikipedia

   en.wikipedia.org/wiki/Off-the-grid

   Off-the-grid or off-grid is a characteristic of buildings and a lifestyle [1] designed in an independent manner without reliance on one or more public utilities. The term "off-the-grid" traditionally refers to not being connected to the electrical grid , but can also include other utilities like water, gas, and sewer systems, and can scale from ...

   Grape Solar manufactures a full line of solar photovoltaic modules for a variety of on grid and off grid applications. [5] Grape Solar's special offering of the 180w made in the USA solar module is the highest efficiency 36 cell solar module available in consumer market.

6. Microgeneration - Wikipedia

   en.wikipedia.org/wiki/Microgeneration

   A major issue with off-grid solar and wind systems is that the power is often needed when the sun is not shining or when the wind is calm, this is generally not required for purely grid-connected systems: a series of deep cycle, stationary or sealed maintenance free batteries (the most common solution) [11]

7. Applications of photovoltaics - Wikipedia

   en.wikipedia.org/wiki/Applications_of_photovoltaics

   The solar array of such off-grid PV system charges a rechargeable battery, which powers a fluorescent or LED lamp during the night. Solar street lights are stand-alone power systems, and have the advantage of savings on trenching, landscaping, and maintenance costs, as well as on the electric bills, despite their higher initial cost compared to ...
