The Challenges of Solar Forecasting: Reducing the Cost of Solar Power Through Research
Carlos Coimbra [UC Merced]
Abstract:
The Solar Forecasting Laboratory at the University of California Merced has collected over 15 months of high quality horizontal and direct normal irradiance measurements at different wavelengths (UV, IR and visible) with the primary objective of developing, calibrating and benchmarking novel and more accurate forecasting models for solar irradiance at the ground level. Without effective forecasting methodologies, neither solar nor wind power plants cannot be effectively connected to the power grid, which presents a major obstacle for high-penetration utilization of intermittent sources. We will discuss different strategies for solar forecasting for both short- and long-term, high spatial and temporal resolution, and forecasting for different solar applications. We will also present a hybrid (GA/ANN) SSL (Stochastic, Self-Learning) methodology that yields very promising results for modeling and forecasting the solar resource, as well as some recent results of the application of our forecasting methodology to model the power output of UC Merceds 1 MW solar farm (SunPower 1-axis TPV).

$1 portable, collapsible solar hot water collector
Making hot water using unmodified trash bags (which were later used for their intended purpose). You can’t beat the ROI on these DIY solar collectors. In cold, cloudy or windy climates, an additional layer of plastic can be put over the top to hold the heat in like a greenhouse. Some day I will replace these with an inclined box and a toilet valve filler, complete with shower head.

Fast Company Magazine has this to say about the Jellyfish:

Jellyfish Wind Power Concept:
What if you could plug renewable wind energy into the wall just like a blender or a toaster? Instead of using power, a wind appliance actually generates it!

Smart-Grid Enabled:
With onboard Wi-Fi/WiMAX the Jellyfish is also smart-grid enabled. Today, wind and solar-powered homes are operated as autonomous points within the local electrical grid. However, they are an overlooked, yet important electrical power resource. If instead, each were harnessed collectively and tied interactively with the local utility grid as a Point-to-Grid (P2G) power generator, or even regulator, considerable economic, environmental and system reliability benefits are possible. By itself, each of these power sources is indeed small in its impact on the power system. In the aggregate, however, the economic value of P2G power is significant, more than enough to offset the initial cost of installing the required control hardware and integrating these systems with the local utility grid. Equally important, the necessary regulatory and energy distribution infrastructure, and hardware components to enable a number of different types of P2G-based systems are already in place today. The convergence of existing distributed electric power and Wi-Fi/WiMAX technologies creates an emerging market opportunity for technology and service providers to enable and accelerate the introduction of various types of P2G-enabled power generation.
