Discussion Overview

The discussion centers around the potential for solar energy to mitigate high electricity costs in California's Central Valley, particularly in the context of residential energy consumption and the challenges associated with installation and efficiency. Participants explore various aspects of solar energy, including cost, installation, and alternative energy solutions.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant notes the high electricity rates in their area, particularly the "300% over baseline" tier, and expresses interest in installing a solar system to reduce costs.
  • Another participant suggests a resource for estimating solar energy potential in the U.S. and mentions the importance of considering available incentives for installation costs.
  • Some participants emphasize the importance of energy efficiency measures, such as upgrading insulation and windows, before investing in solar energy.
  • Concerns are raised about the complexity and costs associated with converting solar energy from DC to AC, which requires additional hardware and professional installation.
  • One participant shares an anecdote about a relative's solar installation experience, noting the variability in energy yield based on weather conditions and potential issues with panel performance.
  • There is a suggestion to consider thermal panels for heating water as a potentially quicker return on investment compared to photovoltaic panels.
  • Some participants discuss the possibility of selling excess solar energy back to the grid as a more economical option than using it for personal consumption.
  • Concerns are raised about the overall costs of solar installations, with one participant estimating that installation represents only a fraction of the total expenses involved.

Areas of Agreement / Disagreement

Participants express a range of views on the effectiveness and practicality of solar energy solutions, with no clear consensus on the best approach. There are competing perspectives on whether to prioritize energy efficiency upgrades or solar installation, as well as differing opinions on the financial viability of selling power back to the grid versus using it privately.

Contextual Notes

Participants highlight various factors that could influence the effectiveness of solar installations, including local climate conditions, roof orientation, and the age of existing home infrastructure. There are also unresolved questions regarding the specific costs and returns associated with different solar technologies.

Who May Find This Useful

This discussion may be of interest to homeowners in California considering solar energy solutions, individuals exploring energy efficiency improvements, and those looking for insights into the financial implications of solar installations.

I'm asking for a direct link to a sales page for 1.5 watt low-pressure sodium lamp for the home.

I agree that reactive power puts an extra burden on the power lines. And there are some additional I2R losses, however, we don't pay for this directly [in the US], so it isn't a way to save money, and it isn't as simple as you suggest. For example, if we live next door to each other, the reactive power from your appliances could be coupled to that from my appliances, with little reactive load seen at the local transformer.

Just FYI: In the industrial arena, we sometimes consider this in order to balance sections of a plant by reversing phase on similar machines. In this way the reactive power from two systems can cancel out. Note that these are typically three-phase systems. Industry is charged for reactive power. We also consider the higher harmonics, usually resulting from high-power switched-mode systems, which can become signficant mainly due to the total harmonic distortion produced.
