Solar power Generation

Consistently offer solar power business to support the development of “power plants that can yield stable income”

With our numerous achievements and rich experience, PR-AZ takes a consistent approach to power plant operation, from securing land, acquiring licenses, and administrative procedures to the design, construction, operation and maintenance of power plants that are best suited to the community. All matters necessary for construction and operation in the power generation business can be handled at once, from the procurement of equipment and materials, such as solar panels and power conditioners, to construction related to power sub-stations and the connection of power lines, to operation, adjustment, maintenance, and security after operation begins.

System Design which will Maintain a Stable Performance for 20 Years

Direct procurement
We can provide the most ideal and high-quality products at reasonable prices through the direct procurement of materials, such as solar panels, power conditioners, transformers, base frames, and even small parts from manufacturers all over the world.
In-house Design
(1)We offer the most optimal degign, taking into consideration regional weather conditions.
(2)We offer design systems, such as in-house structual calculations, that can even cater to regions with salt damage, heavy snow, or heavy snowstorms.
(3)We offer low-cost land construction while preserving the natural environment as much as possible, and perform civil engineering design and construction work based on the topography.
Construction
We have high inspection criteria for construction, which is backed up by our extensive construction track record. Inspections and evaluations from every angle are conducted by third-party organizations upon completion of the construction work. Modifications and repairs are repeatedly performed until high quality standards are cleared.
