Solar System Design Guidelines

Pv disconnect lets you cut off power so that you can work on the system without electrocuting yourself.

Solar system design guidelines.

These are the parts of a grid tie system in order. The designer should choose between the efficiency and the cost of the system. A solar pv system design can be done in four steps. The heart of a photovoltaic system is the solar module.

Power inverter turns the dc from the panels into ac that your appliances can use. Inverter sizing an inverter is used in the system. Roof substrate evaluation iii. Solar modules aka pv panels collect energy from the sun and turn it into direct current.

Pv technology evaluation ii. If you have a 20v solar panel and you have a 12v battery bank you need to use mppt charge controller. Solar panel pv panel 2 charge controller. Base condition 2 cfls 18 watts each 2 fans 60 watts each for 6hrs a day.

Solar home system shs design and installation 95 7 1 design of solar home system shs 97 7 2 installation of solar module 106. To estimate the output power the solar energy assessment of the selected site is of foremost significance. Improve the safety performance and reliability of solar photovoltaic power systems installed in the field encourage industry best practice for all design and installation work involving solar photovoltaic power systems provide a network of competent solar photovoltaic power systems designers and installers to increase the uptake of solar photovoltaic power systems by giving customers increased confidence in the design and installation work. For an off grid solar system you need four basic components.

Strings of modules are connected in parallel to form an array. If your solar panel voltage is different than the battery bank and can t be wired in series to make it match you need to use an mppt charge controller. Size the pv modules different size of pv modules will produce different amount of power. Besides the above components you need a few more things like copper wire mc4 connector breaker meter and fuses etc.

Insolation is defined as the measure of the sun s energy received in a specified area over a period of time. Determine power consumption demands the first step in designing a solar pv system is to find out the total power and. Many photovoltaic cellsare wired together by the manufacturer to produce a solar module. The total energy requirement of the system total load i e total connected load to pv panel system.

To find out the sizing of pv. When installed at a site solar modules are wired together in series to form strings. Topics covered in the design guidelines are. Load estimation estimation of number of pv panels estimation of battery bank cost estimation of the system.
