Abstract
The production on electrical voltage from photovoltaic has fluctuating performance, so it needs to be maintained with optimum control and operational system. Reliability in operation maintenance needs to be maintained, so that the production of electric voltage can be maintained. The analysis is done by calculating the reliability based on the failure rate (λ) that obtained from the value of out of scope contained on the control chart. The variation given is in the form of a failure rate (λ) based on the standard deviation limit. The reliability and availability values are obtained based on the failure rate (λ) while the maintainability values are obtained from the value of repair (r) based on the results of an interview. The failure rate (λ) obtained has a constant value of 0.0274. The reliability value of the photovoltaic system has decreased to 0.55 after the photovoltaic system operates for 22 d. The photovoltaic system has a high availability of 0.998 which is constant at t = 20 d. The photovoltaic system will achieve maintainability of 1 at t = 13 d.
Highlights
The role of electrical energy in daily life has increased significantly
From the out of scope, the failure rate value obtained from the photovoltaic system is 0.0274
The failure rate results obtained indicate that the failure rate has a constant value
Summary
The role of electrical energy in daily life has increased significantly. Even lately the case that occurred in the capital city of Jakarta and surrounding areas, namely mass blackouts or blackout, has been reported in various media. Sunlight is used as an energy source in solar power generation systems or as we often know photovoltaics which can be used as an alternative in increasing the supply of electrical energy. PLTH Pantai Baru Pandansimo is located on the southern coast of Yogyakarta, the location is a large open area, so the sun can shine on photovoltaics throughout the day and windmills can spin with an average wind speed of 4 m s–1 [4]. This condition makes Pantai Baru Pandansimo selected as the location for the development of Hybrid Energy
