Power and energy costs
Cost of power vs Cost of energy
The relationship between cost of power and cost of energy is an important element to assess the feasibility of a solar project.
The chart below plots this relationship for 2 PV systems:
on fixed racks (Blue) and on Vertical Axis Trackers (Brown). Continue reading Power and energy costs
Solar energy in Cranbrook
How much energy can be generated by a solar farm near cranbrook?
Solar irradiation varies year after year and the actual yield depends on how the PV modules are mounted. Fixed racks are simpler, trackers are more complex but may improve significantly the harvest of energy. Continue reading Solar energy in Cranbrook
Solar Irradiation
GHI
The radiation reaching the earth’s surface can be represented in a number of different ways. Global Horizontal Irradiance (GHI) is the total amount of radiation received from the sun on a surface horizontal to the ground. This value is of particular interest to photovoltaic installations and includes both Direct Normal Irradiance (DNI) and Diffuse Horizontal Irradiance (DIF). Continue reading Solar Irradiation
