Photovoltaic Systems

  Photovoltaics, probably more than any other renewable technology, lend itself to gradual expansion. The modular design of photovoltaic systems allows the investors to get involved for a reasonable amount of money and expand the systems as finances are available. By the same token, expandability has saved PV companies from an all-or-nothing sales syndrome. Residential panel producers haven't made a lot of money lately, but a surprising number have managed to stay in business. The flexibility these innovators have demonstrated has gradually reduced the cost of panels, and it has virtually guaranteed solar electricity a place in our energy future.

A photovoltaic (PV), or solar electric system, is made up of several photovoltaic solar cells. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. To boost the power output of PV cells, they are connected together to form larger units called modules. Modules, in turn, can be connected to form even larger units called arrays, which can be interconnected to produce more power, and so on. In this way, PV systems can be built to meet almost any electric power need, small or large.


- Site assessment: geotechnical, environmental, social, climatic aspects;

- Technology assessment: PV panels modules selection, inverter selection, connection to national power grid, O&M requirements;

- Permitting process: validation of power grid connection from the authorities through solutions study, legal framework

- Financial implications: evaluation revenue and operating expenditures,assessment capital expenditures, financial plan and structure (possible cooperation with international financing institutions and grants accessing – EU structured funds)
