ROOFTOP SOLAR - STANDARDS of the country

Image
Standards Code Specification Description International Standards Mandatory requirement SLS 1522 (2016) Sri Lanka Standards Code of Practice for Grid Connected PV Power Systems. This Technical Standards defines the minimal information and documentation required to be handed over to a customer following the installation of a grid connected PV system. This standard also describes the installation, testing and commissioning procedure and documentation expected to verify the safe installations and correct operation of the system. It is for use by system designers and installers of grid connected net energy metered solar PV systems as a template to provide effective documentation to a customer. By detailing the expected installation, testing & commissioning procedure, it is also intended to assist in the verification / inspection of a grid connected PV system after installation and for subsequent re-inspection, maintenance or modifications. Additional, it is written for grid con...

Solar Battery System Types - AC Vs DC Coupled

Image
December 20, 2019 Jason Svarc  What is AC or DC coupling? AC or DC coupling refers to the way solar panels are coupled or linked to an energy storage or battery system. The type of electrical connection between a solar array and a battery can be either Alternating Current (AC) or Direct Current (DC). AC is when the current flows rapidly forward and backwards (this is what the electricity grid uses to operate) and DC is where the current flows in one direction. Most electronic circuits use DC, while solar panels produce DC, and batteries store DC energy. However, most electrical appliances operate on AC. This is why all homes and businesses have AC circuits. DC can be converted to AC using an inverter but, as explained below some energy is always lost in the conversion. The Solar battery evolution Simple DC coupled solar battery systems were once used only for remote power systems and off-grid homes, but over the last decade inverter technology advanced rapidly and led to the devel...

Government Promotions towards Solar Power Generation

Jaya Isura ( ADB FUNDED)     The main objective of this loan scheme is to empower the small and medium scale enterprises including agriculture, fisheries, livestock, floriculture, horticulture, light engineering, printing, tourism, handicrafts, garments, information technology and production industry based on the their trade turnover and to increase the number of job opportunities created. Accordingly, small entrepreneurs engage in the above fields and whose annual turnover is from Rs. 25 million to Rs. 250 million with 10-50 of employees can obtain a loan liable Rs. 50 million maximum limit and loan recovery period of 5 years. If these entrepreneurs engage in export market they can obtain a loan up to maximum limit of Rs. 100 million. As the 50 percent of the interest is paid by the government the interest rate to be paid by the party that obtains the loan is 6.54 percent. Accordingly, small entrepreneurs engage in the above fields and whose annual turnover is from R...
