A Power Purchase Agreement is an agreement between a client and the energy service provider in which the client agrees to make available his/her property to host the energy generation system as well as the option to purchase the energy which is generated from the system. Power purchase agreements range from 8-20 years, during which predictable and stable increases in electricity tariffs are guaranteed. Where applicable, additional generated energy can be sold back to the utility company. The roles of each participant to a typical Solar PV Power Purchase Agreement is set out in the image below.

A photovoltaic power station, also known as a solar farm, is a large-scale photovoltaic system (PV system) designed for the supply of merchant power into the electricity grid. They are differentiated from most building-mounted and other decentralised solar power applications because they supply power at the utility level, rather than to a local user or users.
The solar power source is via photovoltaic modules that convert light directly to electricity. However, this differs from, and should not be confused with concentrated solar power, the other large-scale solar generation technology, which uses heat to drive a variety of conventional generator systems. Both approaches have their own advantages and disadvantages, but to date, for a variety of reasons, photovoltaic technology has seen much wider use in the field. As of 2013, PV systems outnumber concentrators by about 40 to 1.


Carbon emissions trading is a form of emissions trading that specifically targets carbon dioxide (calculated in tonnes of carbon dioxide equivalent or tCO2e) and it currently constitutes the bulk of emissions trading. This form of permit trading is a common method countries utilize in order to meet their obligations specified by the Kyoto Protocol; namely the reduction of carbon emissions in an attempt to reduce (mitigate) future climate change.
Under Carbon trading, a country having more emissions of carbon is able to purchase the right to emit more and the country having less emission sells the right to emit carbon to other countries. The countries emitting more carbon thereby satisfy their carbon emission requirements, and the trading market results in the most cost-effective carbon reduction methods being exploited first. For any given expenditure on carbon reduction, the market mechanism will result in the greatest reduction. Solarparx can assist the individual or organiastion that has already opted for solar installations to further benefit from their installation through the management of their Carbon emission savings generated by their installation.


Parking lots and garage rooftops offer expansive, un-shaded and unobstructed spaces ideal for housing commercial-scale solar energy systems. For years, solar photovoltaics (PV) have proven to be a smart choice for parking facilities for a variety of reasons. With the growing trend of installing plug-in electric vehicle charging stations in some parking lots and garages, energy usage and operating expenses have also increased, making solar PV parking lots a solution for facility owners looking to counteract the increase in energy demand.
Shade structures can be a great addition to any parking lot, as they provide numerous benefits as well as the potential to carry solar panels. Adding shade structures to a parking lot can reduce lighting costs through the installation of energy-efficient LED lighting under the structures in place of the often low-efficiency light poles in many lots. Additionally, as hard as it may be to quantify, elevated shade structures - sometimes called carports - help keep cars dry in inclement weather, provide security from sun and hail damage, and keep cars cooler in the summer.

As part of Solarparx’s Energy consulting service offering, we consider - but do not limit our consulting to:
Lower Demand Charges: Commercial users pay a substantial amount and a monthly bases for demand charges – these charges are calculated based on the peak demand (kilowatt) that they have used in the billing cycle. Through the use of battery storage generator technologies, this peak demand can be capped in order to culminate in a lower monthly demand charge and ultimately a cost saving for the client.
Time-of-Use Optimization: By modelling current operations and optimizing consumer behaviour, significant cost savings can be achieved through some of the Solarparx solutions in order to move the electricity spending curve from peak to non-peak tariffs.
Power Factor Correction: Our experience has shown that many commercial and industrial end users often operate at a sub-optimal power factor, which relates to them paying for energy that they do not actually utilise. Solarparx has various solutions through which this can be corrected in order to prevent energy waste.
