Under a power purchase agreement with SunPower, HP has installed a large-scale solar power installation at its San Diego facility. The panels produces 1.7 million kWh per year, meeting over 10 percent of the facility's energy needs and reducing CO2e emissions by more than 550 tonnes.
In 2008, SunPower Corporation began to generate solar energy at HP’s San Diego facility, using 6,256 solar panels. The panels produces 1.7 million kWh per year, meeting over 10 percent of the facility's energy needs and reducing CO2e emissions by more than 550 tonnes. HP has committed to buy this energy from SunPower for 15 years, saving over $750,000 beginning on day one of the agreement. As part of the initiative, HP and SunPower offered HP employees reduced-rate solar panels for their homes. More than 600 employees requested proposals for solar panels, and over 60 of them have already had the panels installed.

About Solar Electricity
- Sunlight is made up of tiny packets called photons.
Every hour enough of this free, renewable energy reaches the planet to meet the energy demand for the entire world.
- Photoelectric panels consist of many solar cells, which are made of materials like silicon, one of the most common elements on earth. The individual cell is designed with a positive and a negative layer to create an electric field, just like in a battery. As photons are absorbed in the cell, their energy causes electrons to become free, the electrons move toward the bottom of the cell, and exit through the connecting wires. The flow of electrons is what we call electricity.
- By combining solar cells and photovoltaic panels, we can produce just the right amount of electricity to perform a specific job, no matter how large or small.
- Note that we measure energy in units of Watt-hours. A watt is not a unit of energy; it is a measure of power. ENERGY = POWER x TIME
- 1 Kilowatt Hour = 1KWH = 1000 watts used in one hour = 10 100 watt light bulbs left on for an hour
