Know How to Determine the Right Size Solar Grid Tie System for Your Building

Solar PV systems offer lots of benefits to residential and commercial property owners, most remarkably ensures them a renewable and low-cost energy source for usage. However, a few extra benefits will be available based on the type of solar power system you select, and it is necessary to consider the positive and negative aspects of solar on Grid systems and off-grid systems, in order to choose the best option that is perfect for you.


Solar Grid Tie systems are the most familiar and standard type of solar PV system in use throughout the world. This type of power system keeps connected, or “tied” to the local electrical grid and sends excess power back to it for earning revenue from SRECs (Solar Renewable Energy Credits). The solar on Grid systems are capable to maintain power supply even when the solar PV panels don’t get enough sun exposure and can’t produce the adequate amount of energy to meet the needs. The residential or commercial property that is installed with a solar Grid Tie system is often rewarded by the local utility company for the extra power generation. As long as the solar PV panels produce electricity for the user consumption without any grid supply, the power will be free of cost. Even if the house or business consumes more power than the generated amount, it will be billed at a discount on the local electricity rates for extra consumption through the grid.


Determining the right size of your solar grid-tie system is a lot easier than an off-grid system as the local power company maintains all the power-related details for you. There are different ways that you can find a right solar system of this kind. You can look at electricity bills for several months to find out how much is your monthly electricity consumption in kWh and target a solar on a Grid system that would meet your average electricity needs per month.


Once you are done with this, you may like to know how small or large a solar on-grid system will be or to make sure that you have enough space on the ground or roof to accommodate a system like this. Your electrician may recommend you a few things to bring down your power usage or replace the existing appliances in your home to make it more energy efficient.

If your local power supply company follows a tiered billing structure which means you are charged a specific rate for baseline usage and then bigger rates for exceeding that baseline or using a certain percentage of power over the baseline, you should select a solar grid-tie system that reduces the over usage and higher electricity rates which results in a greater savings on your investment. The below-given steps will help you easily determine the right size of solar grid-tie system you need for your building.


  1. Know your average electricity usage per month by going through your electricity bill for several months.  It will be mentioned in kWh.
  2. Calculate your average electricity usage per day (divide your monthly average kWh by 30).
  3. For your location, find the average peak sun hours per day (kWh/sq.m/Day).
  4. Determine the solar grid-tie system size (AC kW) to meet 100% of your electricity usage (divide your daily average electric usage by the daily average peak sun hours for your location).
  5. Divide the result in AC by .77 to get a reduced power rating factor for the system components. It may happen due to temperature, wire defect, component ineffectiveness, etc.
  6. Multiply the above result by 1000 to get watts (AC output) of the system.
  7. Divide the alternating current output of a solar on a grid system by the watt of the module that you desire to use in order to know the exact number of modules you need to cover 100% of your electricity needs.

Solar Water Heating(SWH) System

Each time you feel the warmth of the sunrays on the rooftop or courtyard, it reminds you of a natural energy source is always there for the hot water and space heating needs at your home. It is available in an unlimited amount and at free of cost!

You may be aware that it is possible to convert sunlight into electricity using the solar panels, but it may feel shocking & interesting for you that the same can generate heat energy for solar water heating and space heating. Solar water heating is a cost efficient technology in use to produce heat energy in abundance for your domestic or commercial needs. It will save money on utility bills which will ultimately pay for the SWH installation cost.

Selecting the best solar water heating system may not be easy without proper knowledge; it is recommended to seek for a specialist’s help, who has experience of installing the SWHs and providing quick consultation on them. There are two widely used varieties of solar water heating systems available for your choice.  A Passive solar water heating system does not require any pump induced energy but, the natural gravitation force to help the water circulate from collectors to the tank. It has less number of mechanical parts, reduced maintenance/servicing cost and low expenses for initial setup. Whereas an Active solar water heater is a more expensive, yet energy efficient type having pumps and controls to aid in the process of water circulation.

Both of these solar water heating systems include two key components – a solar collector and a water storage tank. The solar collectors capture the sunrays before converting them into heat energy. They can be of the following types:

  • Flat plate collector:  well insulated and glazed collectors following a flat-plate assembly method
  • Evacuated-tube collector: the transparent and energy efficient glass tubes arranged in rows with little scope for heat loss from them.
  • Integral collector or Batch collector: a system made of single or multiple tanks or tubes kept in an insulated box for long term water storage. It does not fit cold climates due to the risk of freezing pipes in heavy cold condition.

While looking to pick up the best SWH for your home, you need to review the solar water heating systems from all angles. It is the geographical region, climate condition and your home’s position that will be crucial in deciding which solar heating system will be perfect for you.

The active solar heating systems can make up for your extra expenses with lowered utility bills per month. They can be of the following types:

  • An indirect circulation system uses a heat exchanger to transfer heat into the water storage tank from a nonfreezing fluid circulating in it. This kind of system suits the very cold regions where the temperature may fall drastically to cause the pipes freeze at any time.
  • A direct circulation system uses pumps to let the water circulate through the collectors and then flow back into the storage tank. They function well in mild climates where there is no risk of temperature going below the freezing point.

Passive solar heating systems are normally more reliable, durable, less costly to install, but they are not as efficient as the active ones.  They can again be of two types:

  • A thermo-syphon passive system makes the hot water rise from the collector to the crest of a tank without the use of a pump. In this case the collector is fitted underneath the storage tank to make use of the natural gravitational force.
  • An Integral collector-storage passive system assembles hot water in storage tanks or tubes that are placed inside an insulated box and fits the best in mild weather conditions.

An apparent problem in using solar energy is the lack of control on the weather. If you reside in a dark and cold area with only a few sunny days experienced in a year or there is no south facing roof in your residence then the solar water heating may not prove to be as effective as it should.

If all these details can’t eliminate your doubts or confusion, don’t feel worried at all! Solar water heating systems have been in use for a long time but are not extensively used everywhere, therefore asking for advice and guidance from 123 Zero Energy would be a worthy step to take before looking to invest in one.

Buy Solar Grid Tie Systems for Low Energy Consumption

Are you looking for an alternative energy solution with low consumption and budget? Then, a solar grid-tie kit can be just what you need. But how do these solar systems operate, and what makes them so affordable energy solutions?

What is a Solar Grid-Tie System?

A grid-tied solar system is designed to work in conjunction with the grid, providing power supply while offsetting the cost thereof. The system uses a grid-interactive solar inverter – which feeds alternating current (AC) into the grid.

This means any excess powered can be delivered to the transmission grid. In fact, the standard power from the grid can be utilized to make up for any kind of power shortfalls.

Solar Grid Tie

Why Do You Buy Grid Tie Solar Powered Kits?

Solar Grid-tie systems are easy to install and are more cost-effective than stand-alone systems and the systems with battery backup. It’s because of the fact that the system operates using fewer components and the sizing of the system is not dependent on the electric board.

While battery backups are perfect in areas that are prone to power outages, a battery is an expensive component of a solar-powered kit. But it’s far more cost-effective to install a solar grid-tie system with only the essential components.

They can be used both for residential and small-scale commercial application, generally in urban and suburban areas.

Solar Grid Tie

The Grid Parity –

Solar powered grid-tie systems are growing in popularity and are fast approaching grid parity. This means the cost of a kilowatt hour (KWH – a unit of electricity) generated by the AC (Alternating Current) source is equal to or less than the cost of a kWh bought from the grid.

Reaching the grid parity is the point where the renewable energy source stands out as a candidate for widespread development.

How Do You Buy Grid-Tied Solar Kits?

123 Zero Energy has an extensive selection of solar powered kits including solar grid-tie systems best suiting client’s needs and preferences. This makes it a lot easier than ever for customers to find their perfect kit that best fits their requirements and works well within their budget.

Solar Grid Tie

Our solar grid-tie systems use a DC inverter instead of batteries to convert the electricity to AC (Alternating Current). Then, your home can use this energy but if it has a surplus, the energy starts flowing outside the house to the grid.
