Best energy systems


A grid-tied solar panel system is simply a solar energy system that is connected to the electrical grid and therefore, uses electricity from both the solar panel system and the electrical grid.

Because of this, a grid-tied solar system doesn’t have to meet all of the electricity demands of the home.If needed, the home can draw energy from the grid at times (such as on cloudy days or at night) when solar panels are not producing at full efficiency. Likewise, if more energy than is needed is generated by the solar panels of one home, that excess energy will be fed into the grid for use elsewhere.

Benefits of a grid-tied system

A grid-tied solar system has several major advantages over off-the-grid solar systems:

Reliability: Solar panel systems are not perfect. There are bound to be days when efficiency is not what it could be and the system doesn’t produce enough. However, many of your daily (and nightly) activities will continue to require the use of electricity.

Unlike off-grid systems which may run out of power, grid-tied solar systems are less likely to leave you in the dark at inopportune times. If the power generated from your solar panel system is less than optimal, extra energy will be pulled from the grid. The grid essentially acts as a backup for your solar energy system.

Less energy is wasted as a result and the efficiency of your solar power system goes up. Except in the event of a power outage, you will always have access to electricity during any time of day, as long as your system is connected to the grid.


An off-grid solar system (off-the-grid, standalone) is the obvious alternative to one that is grid-tied. For homeowners that have access to the grid, off-grid solar systems are usually out of question.

Here`s why: To ensure access to electricity at all times, off-grid solar systems require battery storage and a backup generator (if you live off-the-grid). On top of this, a battery bank typically needs to be replaced after 10 years. Batteries are complicated, expensive and decrease overall system efficiency.

Equipment for Off-Grid Solar Systems


Hybrid solar systems combines the best from grid-tied and off-grid solar systems. These systems can either be described as off-grid solar with utility backup power, or grid-tied solar with extra battery storage.

Equipment for Hybrid Solar Systems


A solar energy-powered water pump is a water pump running on the electricity that is generated by solar photovoltaic modules.

Applications of solar water pumps

According to each individual need, solar water pumps can be applied for a range of different purposes where pumping water is needed. Main applications include:

  1. Crop and plant irrigation
  2. Srinking and cooking water supply
  3. Industrial water processing
  4. Fountains
  5. Irrigation for Farming
  6. Drinking Water for Livestock
  7. Swimming pools


Solar water heaters also called solar domestic hot water systems can be a cost-effective way to generate hot water for your home. They can be used in any climate, and the fuel they use sunshine is free.


Before you purchase and install a solar water heating system, you want to do the following:

  1. Estimate the cost and energy efficiency of a solar water heating system
  2. Evaluate your site's solar resource
  3. Determine the correct system size
  4. Investigate local codes, covenants, and regulations

Also understand the various components needed for solar water heating systems, including the following:

  1. Heat exchangers for solar water heating systems
  2. Heat-transfer fluids for solar water heating systems


  1. Conventional storage water heaters
  2. Demand water heaters
  3. Heat pump water heaters
  4. Tank less coil and indirect water heaters


Solar street lighting system uses the photovoltaic technology to convert the sunlight into DC electricity through solar cells. The generated electricity can either be used directly during the day or may be stored in the batteries for use during night hours.

Parts of a solar street lighting system

The solar street lighting system comprises of:

  1. Solar photovoltaic module
  2. Battery box
  3. Lamp with charge controller
  4. Lamp post
