Off Grid Systems

Off grid allow you to be completely independent utility company. It comes with all the benefits and features of the grid connected system plus more as you will now have the luxury of an uninterruptable power supply allowing you can live in peace knowing you will have backup power that will ensure the continued operation of all or just your critical loads when the sun is down and no utility bill to pay. There are several variations of off-grid solar power, depending on your needs and budget. All variations of off-grid solar power depends on the number of panels and store electricity in a bank of batteries.

Off-grid stand alone systems operate independent of the utility grid. With stand alone power systems there is absolutely no connection between the system and the grid. Some our packages are flexible and can allow grid interaction at a later time if you decide. Off grid systems will work with or without batteries.

Off-grid solar power gives people electricity to power their homes… Without the electric bill!

Off Grid is perfect for areas where there are no power lines and the local utility company wants to charge an arm and a leg to get their electric power lines out to you.., off-grid power will save you a truck load of money. With off grid power you are your own utility company, when the sun comes up in the mornings you use the power needed and store the excess electricity in batteries and draw from it later at nights. An off-grid inverter can convert the DC energy from solar panels and batteries into AC electricity which powers normal appliances.

An off grid electrical system is a system that generates electricity independently without any assistance from the grid. Solar panels absorb photons of light from the sun, producing DC electric current which must be converted to AC current using an inverter which responds readily provide power to electrical products.

Off grid systems usually requires batteries and a charge controller. The charge controller regulates the power being passed to the batteries to ensure a steady flow of energy in and out. The batteries act as a secondary source of power supply during night-time and rainy or cloudy weather when the panels may not be able to produce at their maximum output. Power is pulled from the batteries when needed during these periods.

  • Operate independently from the grid to provide all of a household€™s electricity
  • Possibility of no electric bills and no blackouts
  • During disasters and public blackouts power will be available to you
  • An investment to your home €“ significantly pushes up property value
  • Batteries will require maintenance
  • Ideal for remote areas where electricity is unreliable or non-existent
  • Sunlight hits the solar module, which is attached to your roof with the mounting racks.
  • The solar (or photovoltaic) cells inside the module then convert the light into electricity.
  • This electricity travels through wires to the charge controller, which senses battery voltage and regulates battery charging – the electricity is then used to keep the batteries fully charged to ensure uninterruptible power.
  • The remaining electricity is then transferred to the inverter and/or the load controller (optional, if you want/need DC electricity).
    • The inverter takes the electricity from the solar module (DC electricity) and converts it into the electricity your home needs to run your appliances, lighting, etc. (AC electricity).
    • The load controller is used for any DC power device you may want to run, and decreases the energy losses experiences when the inverter converts the DC to AC. Nearly all power devices and common appliances use AC electricity. Although, there are DC power devices available.
  • The AC electricity then travels to a standard AC service panel (breaker box), and is supplied to directly to your home/business.
    • The DC electricity (optional) then travels to a standard DC service panel (breaker box), and is supplied to directly to the DC loads in your home/business.
  • ( Optional ) In the event of an emergency (extended cloud cover or unforeseen system disruption), your system automatically begins to draw power from the backup generator and converts it into the electricity you need.

The main components of this system:

  • Mounting racks
  • Solar modules
  • Charge controller
  • Inverter
  • Battery bank

Our Carisol Off Grid Solar Power Systems is available in following standard sizes but we can custom manufactured to any required size.

These are complete turn-key Off Grid solar system packages that allow for easy expansion at a later time by adding just a single panel at a time.

Each Carisol Solar Power System is designed for tropical countries, adjustment to systems designs will be necessary for colder regions.

This system comes with standard PV roof mounting therefore depending on your project location, environmental issues, and roof configuration you may need extra parts for your mounting systems. Please consult one of our sales engineers for additional balance of systems components that you might require.

Q. Is my home or business suitable for solar power?

A. All homes or business is suitable for solar power some might need extra time on the job for the installer base on roofing type.

Q. What size system will I need for my home or business solar power?

A. The minimum size system available at Carisol is 1kW (1000watt). That has a potential output capacity of 1000 watts of DC (direct current) electricity. This DC output is sent directly to the inverter which converts the DC power into 220 volt AC (alternating current) power for use in your home, or export to the electrical grid. A 1kW capacity system will generate about 1470 kWh of electricity per year. You will be able to see from your last electricity bill how many kWh you use at each monthly billing period. There should also be a graph that indicates your last twelve months of usage. This should give you some idea of what size you will require.

Q. What kind of warranty comes with the system?

A. Each of the components comes with different manufactures warranties and conditions ranging from 5 to 25 years. If there are any faults with any component of the installation within the first 12 months, Carisol will arrange for an exchange or repair at no cost to you. The manufacturer warranties for the components will be outlined on your system description and diagram document that will be provided with your quote and agreement.

Q. Does my roof have to have a slope?

A. No as roofing mounts can create any angle requirement needed for system tilt angle.

Q. What if the panels are damaged by a natural event such as hail?

A. TUV testing and certification of our solar panels requires that a 1inch solid ice ball be fired at 50mph straight at the panel without breaking the glass or creating damages to the solar cells however there are those are rare cases where the stones that are bigger can and will break the glass. PV panels can be covered under your home insurance policy so we recommend call to your insurer if needed so you can add your solar power system to your home policy.

Q. How much will I save?

A. An entry level 1000 watt grid connected solar system will save an household using 300kWh per month around an average of 70-90% a year on the power bill.

Q. Will the solar system gives me power at nights?

A. Solar systems needs the sun to operate so at nights you will be taking power form the grid , however if you had produce more than you had use during the days then this will offset the power you take from the utility at nights.

Q. How long will the panels last?

A. A good quality solar panel will last a lifetime and comes with a 25yrs output warranty, it€™s important to look for the TUV quality certification symbol on product or brochure before purchasing.
