The Ultimate Solar Term Glossary: What You Need to Know


A large portion of the skirmish of finding out about the sun oriented vitality industry is understanding the language. Whether you’re simply beginning or need a little refresher, audit our basic definitions beneath to increase better knowledge on the sunlight based industry.


A sun based inverter changes over direct present (DC) energy to exchanging current (AC) power, either for individual sun based boards or for framework associated sun oriented power frameworks. DC control delivered by a sun oriented exhibit must be changed over to AC power so it can be utilized as a part of family unit apparatuses — without an inverter, the vitality from your sun based boards can’t undoubtedly be put to utilize. There are three fundamental sorts of inverters:

Microinverters are introduced in individual sunlight based boards and are perfect for little sun oriented power frameworks.

String inverters are perfect for vast private or little business setups.

Focal inverters are perfect for vast scale frameworks like sunlight based ranches.


A kilowatt (kW) is a measure of force — the request at any given time. A kilowatt-hour (kWh), then again, is a measure of vitality — the utilization of control over a timeframe. A kWh is the power request (kW) increased by the aggregate sum of time the power is being utilized (in hours). Along these lines, if a 30-watt knob is running for 24 hours, 720 watt-hours or .72 kWh is expended (30 watts times 24 hours).

The normal family unit expends around 30 kWh every day. On the off chance that your sun oriented boards get five hours of pinnacle daylight every day, you require 6 kW of yield (30 kWh partitioned by 5 hours — that is your request) to cover 100% of your vitality utilize. A regular sun oriented board can create somewhere around 250 and 270 watts of pinnacle power amid perfect conditions, which implies you’ll require around 24 sunlight based boards to make a 6-kW exhibit.

One megawatt (MW) is equivalent to one thousand kilowatts (kW). One megawatt hour (MWh) is proportional to 1,000 kilowatt-hours (kWh) constantly devoured in 60 minutes. One MW can control a normal of 164 homes, however that number can change altogether by district.

See Also Kilowatt/Kilowatt Hours


Net metering is a charging framework that permits clients with a sun powered cluster to send overabundance or unused sun oriented vitality back to the utility lattice for adjacent clients to devour. This framework helps sunlight based power clients increase noteworthy reserve funds every month on their service bills.

At the point when vitality request is low amid the day, a run of the mill sun powered board framework delivers more power than one family unit can use. Net metering permits clients to pick up credits for the overabundance vitality their sun powered board frameworks create amid this time. At that point, amid the night or times of pinnacle utilization, a family can utilize these credits to devour power that is as of now paid for.

Net metering benefits differ between states. To find out about your state’s net metering strategies, look at the Database of State Incentives for Renewables and Efficiency® (DSIRE).


The term photovoltaic (PV) originates from two root words: “photograph” (light) and “voltaic” (voltage).

In material science, “photovoltaic” alludes to anything that produces power when presented to light or other brilliant vitality. Sunlight based cells, sun oriented modules, and sun oriented boards are regularly alluded to as PV cells, PV modules, and PV boards to express how their power is created.

Real-time pricing (RTP) is a type of time-varying rate (TVR): it enables clients to pay at the real cost of power at any given time and save money on utilities by modifying their own vitality use amid times of high or low request.

RTP arrangements shift from state to state, and the cost of electric power can change altogether inside a 24-hour time span — cost relies on upon an assortment of components, including expected free market activity, temperatures, fuel costs, or even a generator blackout. In spite of these cost vacillations, nonetheless, clients tend to pay a similar value paying little heed to when their vitality is devoured.

With RTP, a client gets a value motion in short interims that mirrors the genuine cost of expending power amid that time. This valuing framework requires the establishment of a keen meter to transmit power cost information, however can spare clients a normal of 15% on their service bills.

A solar array is a gathering of sun based boards wired together to make the wanted vitality yield. The regular private sun oriented cluster comprises of 20–25 sun based boards to cover 100% of its vitality utilization.

A solar cell — otherwise called a photovoltaic (PV) cell — is the fundamental part of a sun powered board. At the point when daylight hits the cell’s surface, the electrons in the cell are thumped free and power is created.

Each sun based cell is commonly made of a thin, solidified silicon wafer. A sunlight based cell is octagonal fit as a fiddle, pale blue dark in shading, and around 156×156 mm in size. An extensive heap of sun powered cells can be wired together into a sunlight based board, or a cell can be cleaved to pieces and fit into little devices like adding machines and computerized watches.

A standard sun powered cell can produce around 1 or 2 watts of force; some sun oriented cells can create as much as 3 to 4.5 watts. A run of the mill sun oriented board is made of 36 to 40 sun oriented cells.

A sun oriented homestead is frequently alluded to as a sunlight based farm, sun oriented field, or sun powered stop. Spreading over between a section of land and 100 sections of land of sun powered boards, a sun oriented homestead permits a group to receive the rewards of a sun powered power framework without acquiring, introducing, or keeping up individual frameworks. Sunlight based homesteads ordinarily introduce sun based boards on towers that can track the sun to deliver a higher vitality yield every day contrasted with a regular — static — private sun powered exhibit.


See Solar Panel


At the point when sun powered cells are wired together to create bigger measures of force — regularly in a heap of 36 to 40 cells — they frame a sun oriented board. The term sun based board is regularly utilized conversely with sunlight based board. To finish sought current and voltage, sunlight based boards are wired together to shape a cluster.

The normal family unit will require 20–25 sun based boards in its sunlight based cluster to cover 100% of its vitality utilization — however you’ll need to utilize a sun oriented mini-computer to decide what number of boards your family’s normal vitality utilization will require.

Time of Use (TOU) is a sort of rate-differing use (RVU) estimating: it separates the 24-hour day into three or four pre-characterized time squares, not in view of real use at those particular times. This layered valuing structure will stay settled consistently over seasons. TOU evaluating urges clients to move their power utilization to certain time pieces where request is low and expenses are less expensive.

It might be a significant test to wrap your head around the sun based industry’s vernacular interestingly. Bookmark this glossary just on the off chance that a word or expression abandons you scrambling.
