What Is An Off Grid Solar System And Who This Is For

Solar power systems are great alternatives to your typical electrical systems. Aside from obvious benefits like energy-efficiency, solar power systems are also cheaper and are friendlier to the environment.

There are three types of solar power systems: 1) on-grid, 2) off-grid, and 3) hybrid solar systems. This article will tackle and focus more on the second type, the off-grid solar power system.

As in their name, solar power systems like a home off grid solar system operate on solar power. They then convert that solar energy into electricity.

Also called stand-alone power systems, off-grid solar systems are basically not connected to any electrical power grid. Because of that, they are equipped with a high-capacity battery bank to store the electricity harvested by the solar panels.

Because of the battery storage, an off-grid solar system is perfect to use in long winters, during adverse weathers or emergencies. During these conditions, there is a high possibility that power outages will occur which can sometimes last from hours to days to weeks.

With an off-grid solar system, your home will not be affected since the system can provide electricity for you. Just make sure that your solar system is designed to have the capacity to meet the electricity needs of your home.

This type of solar system is also perfect to use in remote areas located far from the local electrical grid or in areas that are prone to power outages.

How Many Solar Panels Will You Need

How many solar panels will you need? That depends entirely on how much energy you need to generate. Every situation is different and depends on your homes average energy use, hours of sunshine per day, roof angle to the sun, size of your roof and a number of other factors.

There are solar panel calculators online or Sunstores experts can help you specify the right solar system for your needs. As an average, a three bedroom home run completely off-grid would require around 4.4kw of solar panel output. A smaller energy efficient building may only require 2.2kw. Much depends on those conditions above.

Sunstore would be happy to discuss your options and help you decide how many panels you need.

What Size Solar Panel Kit Do I Need

If you’re picking out a home solar system kit or sizing solar panel for shed, you need first to consider the size of your battery and your daily power usage. Suppose you have a 12 volt 200ah battery only 80% of that is usable due to depletion limitations. In that case, you only have 160 amp-hours of energy to draw on. If you learn that you typically can last two days with power from that battery, you consume 80 amp hours daily. A 100-watt 12 volt solar panel will produce an average of about 30 amp-hours per day , which means you would need three 100-watt solar panels or one 300-watt solar panel to fully recharge your battery on an average day.

Utility Bill Rate Design

Good electricity rate design allows you to save money when you save energy. This might sound intuitive but not all provinces are same. Superior designs have low fixed monthly fees and tiered electricity rates. Inferior designs have high fixed fees and flat electricity rates.

Ontario scores near the front of the pack when it comes to these factors having time-of-use rates and fixed monthly fees of $26 .

For example, reducing your electricity bill from 1,500 to 750 kWh per month will save you 54% on your electricity bill in British Columbia, 48% in , but only 43% in Ontario!

Note that fixed monthly fees dont disappear even if you switch to solar youll pay them as long as you remain connected to the grid. But this isnt a bad thing $26/mo is a small price to pay for using the grid as your back-up energy source!

The only way to completely remove your fixed costs is to go off the grid, something most homeowners in Ontario dont do because of high battery costs.

Disconnecting from the grid also means that you wont be able to participate in your utilitys net metering program.

An off-grid solar system is not connected to the electricity grid and requires battery storage. Off-grid solar systems must be designed correctly in order to generate enough power throughout the year and have the necessary battery capacity to meet the installed locations electrical energy requirements or demand.

In Africa, we are very fortunate with abundant sunshine. A backup generator or alternative back up power source may be necessary to supplement your electrical demand and recharge the batteries during times when the batteries are inadequately charged due to very bad weather patches or other unforeseen circumstances. We recommend that the size of the backup power source should be adequate to supply energy to your house and charge your batteries at the same time.

Why Off Grid Solar System Packages With Batteries

For those living off the main grid due either by choice or circumstance, an off-grid system is one that provides them with electricity such as rooftop solar or off-grid solar power systems. These solar technologies provide their own sources through renewable means like solar panels not connected to outside grids nor reliant upon complicated transmission towers carrying lines down miles into each homes property boundaries they go about running everyday life, as usual, free from reliance upon any paid.

An off-grid standalone solar system includes four main parts, including a solar battery bank, solar panels, a solar inverter or an MPPT solar charger controllers , a solar charger controller, and a backup generator which is optional but comes in handy when there is a power shortfall caused by low sunshine or changes in the climatic conditions. Off-grid systems are built to provide power for homes that live without electricity and these sources can be either AC or DC, and they vary depending on the off-grid system. Some examples include solar inverters using common solar panels or backup generators powered by wind turbines .

Implication Onto Electricity Bill Management And Energy Investment

Customers have different specific situations, e.g. different comfort/convenience needs, different electricity tariffs, or different usage patterns. An electricity tariff may have a few elements, such as daily access and metering charge, energy charge or peak demand charge . PV is a promising option for reducing energy charge when electricity price is reasonably high and continuously increasing, such as in Australia and Germany. However, for sites with peak demand charge in place, PV may be less attractive if peak demands mostly occur in the late afternoon to early evening, for example residential communities. Overall, energy investment is largely an economic decision and investment decisions are based on systematical evaluation of options in operational improvement, energy efficiency, onsite generation and energy storage.

What Is An Off Grid Solar System

Amazon.com : ECO

An off grid solar system is an independent, stand-alone energy system. Its designed to produce electricity without being connected to an existing grid, but it can also store and distribute that electricity when no other power sources are available. The system uses the power of the sun to generate electricity, and it stores that energy in batteries that can be used whenever needed. Thats why its sometimes called solar photovoltaic energybecause it uses solar panels to generate electricity and PV panels to store it.

What Are The Different Types Of Off Grid Solar Systems

There are typically five types of off-grid solar systems. Before you purchase and set up your off-grid solar system, it is important to know more about the product. This article will explain the different systems.

DC only system

DC only systems are smaller that are designed to power mainly lights and low energy consuming devices like your monitoring equipment. They are also perfect to use on DC-powered appliances having 12 voltages or lower.

This system either uses a solar panel or wind generator that generates DC power. This power is then used to charge the battery bank.

Here, there is no solar inverter. DC power is directly fed to your lights and/or appliances. This system typically has no back-up generator hence, you need to ensure that your system is sized to handle your loads in emergency situations.

Mixed DC and AC system

This hybrid system is similar to your DC only system but with the addition of an AC inverter. This is still designed for powering light or low energy equipment.

With the AC inverter, you are able to power appliances that have 230 volts.

Nevertheless, since it is a small system, there is also no back-up generator. Thus, it must be designed in such a way to ensure that it can handle your loads during emergencies.

AC only system

With the solar inverter, the DC power is converted into AC power that can be used to run your typical household electronics and appliances.

Choosing The Right Battery For Your Off Grid Solar System

The choice of battery is as important as the solar panels that generate electricity. Batteries are used to store the electricity from solar panels, and they determine how long an off-grid solar system can run without sunlight. There are a few factors to consider when choosing the right battery for your off-grid solar system: Lifespan The lifespan of a battery can determine how long your entire system will last. Its important to match your power needs with the lifespan of the battery. Cycle life This refers to the number of times a battery can be charged and discharged. A battery with a high cycle life can be charged and discharged frequently without losing charge capacity. Maintenance Maintenance is an important part of owning any piece of equipment. Batteries are no exception. Some require more maintenance than others.
