   CT Solar Lease owns and sells the RECs generated by the system, but turns over all but $15/REC plus 100% of the sale over $30 or 50% of the sale of the REC up to $30/REC to the homeowner in a Solar Dividends account for maintenance and to allow the purchase of the system at the end of the lease. RECs have been selling for from $18 to $24 each.

3. Central solar heating - Wikipedia

   en.wikipedia.org/wiki/Central_solar_heating

   Central solar heating is a sub-class of 'large-scale solar heating' systems - a term applied to systems with solar collector areas greater than 500 m 2. Aquifers, boreholes and artificial ponds (costing €30/m 3 ) are used as heat storage (up to 90% efficient) in some central solar heating plants, which later extract the heat (similar to ...

   The operating conditions' optimization of this system is the main challenge, because there are two opposing trends of the performance of the two sub-systems: by way of example, decreasing the evaporation temperature of the working fluid increases the thermal efficiency of the solar panel but decreases the performance of the heat pump, and consequently the COP.

6. Solar thermal energy - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_energy

   A collection of mature technologies called seasonal thermal energy storage (STES) is capable of storing heat for months at a time, so solar heat collected primarily in Summer can be used for all-year heating. Solar-supplied STES technology has been advanced primarily in Denmark, [15] Germany, [16] and Canada, [17] and applications include ...
