# Produce Power With Solar Panel System

by John Peter Discussion Point

Solar panels (PV or PV modules) generate direct or direct electrical current. It is the same type of electricity produced by the car battery or other battery. In our home, appliances use another type of electricity called alternating current or alternating current. DC power flows in only one direction, while alternating current is fast, providing some transport benefits.

Conventional Home Appliances

To use solar power to power conventional home appliances, you will need a solar inverter that converts DC to AC. A small system doesn't need inverters to charge batteries or power small electrical devices (like cell phones and personal music players), but if necessary, voltage converters or selectors using the right converters

The basic electrical primer helps to clarify all this:

·         Volt - a unit of electrical potential

·         Amps - Current flow rate

·         Watts - Rated Power or Consumption

·         Now consider these values ​​in terms of energy and energy.

Energy is the rate at which energy is saved, such as the speedometer of your car, and is measured in watts

Energy is a measure of power over time, such as an odometer in a car, and is measured in watts or in lethal hours

One of the best examples is the incandescent bulb in your old school. If the rated power is 60 W and you leave the light on for an hour, you consume 60 W (ie 60 W x 1 hour). Consumption can thus be measured by the following formula:

Power (W) x Time (Hours) = Power (Watt Hours)

When measuring the car, the odometer calculates the distance traveled. The utility bill refers to the number of kilowatt hours used each month (kWh or 1000Wh).

Factors And Power Of Solar Panel

How does the power factor of a Solar Panel System affect the amount of energy a panel produces? Simple - with all the stability a high power solar panel will produce more power over time than a low power panel. Solar panels will produce 100 watts twice as much energy as 50 watts of solar energy in one place at the same time.

It is also worth noting that the rated power of solar panels depends on so-called standard test conditions (STCs) under laboratory controlled conditions. The STC rating allows solar panels to compare solar panels using the same scale. However, since this rated power reflects ideal laboratory conditions, the device is likely to use less power in practice.

Pv Modules

PV modules also have ratings. The rated power of the board is equal to the operating voltage multiplied by the operating current: watts = volts x amps. The amount of energy per watt that a plate will produce is the power of the plate and the number of hours of sunlight at full intensity it receives.

For example, a solar panel producing 100 watts for two hours would produce 200 watts of electricity per hour. Insulation values ​​are also STC-related and location-based. You can find it in spreadsheets in most places in the US and around the world. It is very likely that the actual number of watts hours a board generates will be less than this theoretical value due to several factors affecting the system components. There are standard factors for correcting energy losses in the real world, but our current emphasis is on the basic principles of electricity.

Solar And Voltage Panel

PV Panels modules have three different voltage parameters that are easy to understand.

Rated voltage: The nominal voltage of the board can also be called "colloquial voltage". When we talk about the capacitance of panels and other system components, we mainly use rated voltages. The rated voltage actually refers to the electrical capacity of the battery for which the unit is suitable for charging; This is a term left over from the days when only solar panels were used to charge the batteries. The actual voltage rating of the panel varies depending on the lighting conditions and temperature, so there is never a defined voltage for the panel operation. The rated voltage allows us to see at a glance that the board is compatible with a particular system.

Voltage at maximum power or VPM: This is the highest voltage at which the circuit board is connected to the system and can operate at maximum efficiency.

Open Circuit Voltage or Wok: This is the maximum voltage that the circuit board can generate when it is not in contact with the circuit or system. VOCs can be measured with a meter that connects directly to the end of the panel or the end of the integrated cable.

Solar Panel And Power

The panel also has two different existing labels: (Imp) and (Isc), both listed in Amps. Similar to Imp Power, Imp, Vmp: This is the maximum current available when the board is operating at the highest efficiency in the circuit. Short circuit current (Isc), similar to a wok, is a measure of the current that the pointer will display in contact with the positive and negative.
