Guidelines for optimizing rooftop projects in Dubai There are many parameters that determine the optimization of a system. Here are some that we will analyze. Understanding the legislation – Net metering Calculating your consumption Calculating and predicting your consumption over It is very important to understand the legislation in the next years is important to determine the size of order to plan accordingly your system your installation Calculating the available area Choosing the equipment Roof top, ground mounted, carports, facade are Once you know what should be your size and area some of the options for installation area. of installation, you can choose the proper equipment.
“In order to fully gain the financial benefits of the net metering scheme, you should install a system that, during its lifetime, produces at the most, the amount of electricity that you will be consuming over the same period”
Net-metering scheme These are the main important points of the legislation that we should consider How it works What happens with the excess electricity Any surplus of electricity will be offset from the The electricity produced by the solar system is investor’s bills in the following months. An indefinite available for the investor’s consumption and any rollover is applied, so any surplus will be carried excess is fed back into the grid. forward to the next bill. Limitations Available area for installation The capacity installed should not exceed the PV modules can installed almost everywhere, but maximum load allowed at the investor’s premises. inside the same plot where is the consumption. The Moreover, DEWA could impose a lower threshold financial optimum solution is to install the on the should it be justified by technical limitations related rood top since the cost will be less. to the integration of the PV system into the power distribution grid.
Net-metering scheme Example with shortage of electricity production The electricity produced by the PV system reduces the amount of energy that a customer has drawn from the grid. If, at any point in time, more energy is produced than consumed, the excess is exported to the grid. The monthly energy bill will only reflect the net amount of energy consumed.
Net-metering scheme Example with surplus of electricity production The following billing period, the credit will be offset If during a billing period more energy is exported than against net consumption. If during the course of several imported, the invoiced value of electricity will be zero consecutive months more energy is produced than and the surplus electricity will be shown as a credit imported from the grid, the credit accumulates and is which can be brought forward in the following billing carried over to the following months. period

Choosing the size of the project Basic steps Calculate the yearly consumption Draft calculation for energy production In Dubai region, the energy production can vary The real yearly consumption can be easily from 1.700 KWh/KWp/year to 2.000 calculated by adding 12 consecutive electrical bills. KWh/Kwp/year, depending on the architecture of It is also necessary to predict of possible any the solar system. This is a difference of 15% changes in the close future. between the two figures. Checking the available area Orientation and inclination of the PV panels The installation should be in the same plot where is The main parameter determining the energy the consumption, so the area is limited to this. First production is the orientation and inclination of the choice will be the roof top, then ground mounted, PV panels. Since we are installing on an existing then car ports and then the facade. building, in most cases we need to follow the orientation of the building and the inclination of the roof.
Orientation and inclination Possible variations Energy Yield according to orientation / inclination 2050 2000 1950 1900 1850 1800 1750 1700 1650 1600 1550 0 20 40 65 90 The black line is how energy yield is affected at orientation 0 to 90 degrees, for a flat roof project, with PV panels at optimum inclination of 24 o . The red line is how energy yield is affected at orientation 0 to 90 degrees, for horizontal PV panels. The blue line is how energy yield is affected at orientation 0 to 90 degrees, for a flat roof project, with PV panels at inclination of 10 o . The green line is how energy yield is affected at orientation 0 to 90 degrees, for a flat roof project, with PV panels at optimum inclination of 20 o .
Orientation and inclination Flat roof, steps for designing Check available area Check orientation of the building If the area is not enough, following the orientation of If the available area is enough for installing the the building will help to install more panels. preferred size of project, we optimize both the Maximum deviation in such case is 45 o that still will orientation to the south and inclination at 24 o . This provide a high yield. will give us the highest yield. Checking inclination of panels Checking shadow Another trick to fit more panels when the area is not In some cases it is more efficient to use the enough is to lower the inclination from optimum. optimum inclination with the best orientation and This will enable us to bring one row closer to the minimize the distance between rows. The shadow other without creating shadows. will affect the production but it might not affect more than 3-4%.
