NOVELTY - A foldable solar collector e.g. solar umbrella (1211) has a parabolic reflector that can be operated in closed and open positions. The parabolic reflector has a parabolic surface that collectively reflects and concentrates the sunlight. A solar receiver receives concentrated sunlight from the parabolic reflector and then convert it to usable energy.    USE - Foldable solar collector e.g. solar umbrella for concentrating solar power onto receiver of PV cells, and then converting concentrated solar into usable energy.    ADVANTAGE - Provide a lightweight, small volume and highly portable solar collector in the form of solar umbrella made up of components that can be folded up into a small package and fit inside of e portable canister or cover. Perform a portable solar energy collection to enable electrical and hot water generation on electric vehicles, and anywhere on the ground that sun is prevalent at low cost. Enable solar umbrella to provide shading and can be made part of a shelter unlike the existing domestic solar panels which require roof top installation which can be expensive and inconvenient. Enable solar umbrella to directly provide power to window type air conditioner, TV and computer without the need for connection to the electricity power grid which will contribute to the reduction of installation and permit processing cost as well as the time needed for PV generation. Allows connection of solar umbrella to the house electrical panel after the grid tie in, using a switch to alternate between the solar electrical supply and the grid supply, making co-phasing with the grid system as the solar receiver generated power is never in-line with the grid system, and if so desired, the solar umbrella can be hooked into the grid system in a traditional style with co-phasing required at the electrical panel of the residence or building.    DESCRIPTION OF DRAWING(S) - The drawing shows the perspective view of the unfolded solar umbrella.
